When I visit Hawaii, I always hope to catch a glimpse of a rainbow stretching across the sky.
The islands earn the name “Rainbow State” because rainbows are so common, and seeing those colors makes any trip special.
The best time to see rainbows in Hawaii is during the rainy season from November to March, especially in the morning when the sun is low.
Rainbows appear more often in Hawaii than anywhere else I’ve been. Warm sun and brief showers create the perfect mix for rainbows, and spotting that colorful arc lifts my mood every time.
If you want to know where and when your chances are highest, you’re in the right place.
I’ll share what I’ve learned about why Hawaii is the ideal place for rainbows and how you can make the most of your visit.
There are a few simple tips that helped me see rainbows more often, and I’m excited to pass those along so you don’t miss out on this must-see part of the Hawaiian experience.
Understanding Rainbows in Hawaii
Rainbows in Hawaii are a stunning natural wonder that attract people from all over the world.
The islands make it easy to spot a multicolored arc, especially when conditions are just right.
What Makes Hawaii Ideal for Rainbows
People call Hawaii the “Rainbow State” because rainbows are so common here.
Warm trade winds bring in moisture from the ocean, and the mountains force the moist air to rise.
This mix leads to gentle rain showers while the sun is still shining.
Clean air helps too.
Hawaii has less pollution, so the sun’s rays travel easily through the sky.
Water droplets from quick showers or waterfall spray create the perfect setting for a bright rainbow.
Timing matters.
After a morning or afternoon rain, I often see a rainbow stretching over green valleys or near waterfalls.
Places like Rainbow Falls in Hilo and Waimea Valley are famous for their rainbow sightings.
The Science of Rainbows
A rainbow forms when sunlight shines through water droplets in the air.
Each droplet acts like a tiny prism.
The light bends as it enters the droplet, reflects inside, and bends again as it leaves.
This process splits the light into different colors.
Both the angle of the sun and the size of the droplets matter.
For the best rainbow, the sun should be low in the sky, like in the morning or late afternoon.
Larger droplets from heavy rain or waterfalls make brighter, more vivid rainbows.
Some people go on a “rainbowchase” after showers because double rainbows or even full-circle rainbows can appear in Hawaii’s unique weather.
It all depends on sunlight, rain, and the right viewing position.
You don’t need any special equipment—just your own eyes and a bit of luck.
Colors of the Rainbow
A typical rainbow in Hawaii shows a seven-color spectrum.
These colors are red, orange, yellow, green, blue, indigo, and violet.
I learned the acronym ROYGBIV to remember the order.
Rainbows often look especially bright against dark clouds or lush green backgrounds.
Sometimes, I see a double rainbow, with the outer arc showing colors in reverse order.
The space between the two bands looks darker; this is called Alexander’s band.
Here’s a simple list of the rainbow colors from top to bottom:
- Red
- Orange
- Yellow
- Green
- Blue
- Indigo
- Violet
Each color forms as the droplet bends and reflects sunlight at slightly different angles.
This creates the beautiful, multicolored arc that makes Hawaii’s rainbows so special.
The Best Time to See Rainbows in Hawaii
The best time for rainbow viewing in Hawaii depends on sunlight, weather, and even which island I’m on.
By paying attention to local patterns, I can catch vibrant rainbows more often, especially during the wetter months.
Morning vs Afternoon Viewing
Early morning and late afternoon are the best times for finding rainbows across the Hawaiian Islands.
During these hours, the sun sits lower in the sky, making the angle just right for sunlight to pass through rain and form a rainbow.
I like to head out right after a brief rain shower, as the sun starts coming out.
At these times, the sky can have vivid rainbows that last longer.
While noon offers plenty of light, the high position of the sun makes rainbow-forming angles rare.
Some photographers prefer the morning because the air is clearer and fresher.
Others like the unique colors that appear closer to sunset.
For the best chances, I keep the sun at my back and look toward areas where rain is still falling.
Popular places like Waimea Valley and higher elevation lookouts often give me the best views after rainfall.
Seasonal Weather Patterns
Rainfall in Hawaii changes with the seasons.
The rainy season happens from November to March.
During winter, passing showers mix with sunshine to create rainbows across the islands, especially after short bursts of rain.
The sun’s lower position during winter also helps form rainbows more often.
From April to October, the weather is drier on most islands, so rainbows are less common but still possible.
The Big Island and Kauai often get sudden brief showers, even outside the rainy season, which is lucky for rainbowchase fans like me.
Impact of Microclimates
The Hawaiian Islands are famous for microclimates.
Just driving a few miles can take me from dry, sunny weather to a quick rain shower.
These small climate zones happen because of mountains, trade winds, and the surrounding ocean.
For rainbowchase adventures, I check out places known for frequent showers.
On Oahu, the Koʻolau Mountains almost always have some moisture in the air.
On Maui, upcountry areas get quick showers followed by bursts of sun.
Waimea Valley and Hilo on the Big Island are other reliable spots.
Here’s a quick table of top rainbow viewing locations with frequent microclimates:
| Island | Top Spot | Why It Works |
|---|---|---|
| Oahu | Pali Lookout | Mountain rains |
| Maui | Upcountry Maui | Elevation/sun |
| Big Island | Hilo | Frequent rain |
| Kauai | Hanalei Valley | Coastal showers |
Moving between these microclimates increases my chances of catching rainbows at almost any time of year.
How to Read the Weather Forecast
To make the most of my rainbowchase, I always check the weather forecast before heading out.
I look for days when forecasts mention scattered showers mixed with sun, especially in the morning or late afternoon.
Here’s how I plan:
- Check for rain chances: Even a 20% chance can bring quick showers perfect for rainbow viewing.
- Look at radar maps: These show rain bands moving across the islands, so I know where to go.
- Note sunrise and sunset times: Lower sun angles in these periods are best.
- Pay attention to wind direction: Trade winds often push rain clouds against mountain ranges.
By reading the forecast closely, I plan my outings and increase my chances for bright, colorful rainbows.
I always bring my camera, as a rainbow can appear and vanish quickly in Hawaii’s changing weather.
Top Rainbow Locations Across the Hawaiian Islands
From lush rainforests to towering waterfalls, I’ve visited many places where Hawaii’s famous rainbows appear.
Some spots have paved paths and clear viewing areas, while others offer hidden gems among trees and rivers.
Rainbow Falls and the Wailuku River
Rainbow Falls, or Waiānuenue, sits in Hilo inside Wailuku River State Park.
I enjoy how close I can get to the falls, thanks to a paved path and a wheelchair-friendly viewing platform.
The waterfall stands about 80 feet tall.
If I visit early in the morning, the sun often creates bright rainbows through the mist.
A giant ancient banyan tree offers shade while I watch the falls.
It’s one of the most famous rainbow spots in Hawaii, and it’s open daily with no entry fee.
For more details and tips for visiting, I check the best place to view a rainbow in Hawaii guide.
Akaka Falls and Surrounding Trails
Akaka Falls is another favorite location of mine, found north of Hilo.
The main feature is ʻAkaka Falls, which drops 442 feet into a gorge below.
Walking the paved loop trail, I see dense tropical plants everywhere.
Lookout points offer views of ʻAkaka Falls and smaller falls like Kahūnā Falls.
On clear mornings after rain, I often spot rainbows across the mist at the main lookout area.
Along the trail, the path is easy to walk, but there are sections with stairs, so it’s not as accessible as Rainbow Falls.
The constant water spray, lush ferns, and steep cliffs make the views dramatic and memorable.
Kauai’s Scenic Rainbow Spots
Kauai, the Garden Isle, delivers some of the most beautiful backdrops for rainbows.
The Waimea Canyon area, with its deep valleys and patchworked colors, looks stunning when rain showers pass through.
After a light rain, I often spot rainbows arching above the red and green cliffs.
Hanalei Valley is surrounded by taro fields, mountains, and rivers.
I like coming here right after sunrise or in the late afternoon, times when rainbows tend to appear above the valley.
The lookout point by the main road gives a clear view over the entire area.
The lush nature and rolling hills create a perfect setting for rainbows.
Chasing Rainbows in Maui and the Big Island
On Maui, I find lots of rainbows in Upcountry spots around Kula and along the road to Haleakalā.
The higher elevation and cooler air bring regular light showers and dramatic double rainbows.
After rainfall, the slopes are often dotted with small waterfalls and rainbows in the distance.
The Big Island also has many places for rainbow lovers.
Besides Rainbow Falls, the Pe’epe’e Falls and Boiling Pots area upstream are great for catching misty rainbows, especially after heavy rain.
I recommend checking out these top rainbow spots for a full list of locations across the islands.
Some beaches and open fields offer clear skies and rainbows after a quick rain, especially in the mornings or late afternoons when the sun angle is low.
Each island is unique, but the mix of waterfalls, mountains, and changing weather makes rainbow hunting a memorable part of my time in Hawaii.
Hiking and Outdoor Activities for Rainbow Viewing
When I search for rainbows in Hawaii, I find that hiking, short waterfall walks, and safe viewing spots all make the experience better.
Flash floods and changing weather matter too, especially if I’m exploring wet areas with lush plants and animals.
Best Trails for Rainbow Hunters
I like to look for rainbows by hiking on trails near waterfalls and rivers.
On the Big Island, the trails around Rainbow Falls attract many people because they are not too hard, and you can see rainbows early in the day, especially after rain.
If I want to see unique plants and animals, I choose paths that go through rainforests.
Wide, open trails give me a better view of rainbows, especially when sunlight shines through the mist.
I always check the weather before heading out, because recent rain can bring more rainbows but also makes trails slippery.
Here’s a simple table with a few top trails and what makes each special:
| Trail Name | Location | Features |
|---|---|---|
| Rainbow Falls Loop | Big Island, Hilo | Waterfall, rainbows, easy |
| Manoa Falls Trail | Oahu | Lush flora, short hike |
| Waimoku Falls Trail | Maui | Long hike, tall falls |
Short Hikes Near Waterfalls
I often pick short hikes when I want to reach a beautiful waterfall and maybe see a rainbow without a long walk.
The path to Rainbow Falls near Hilo is less than half a mile, so I can bring friends or kids of any age.
I can view the falls and possible rainbows almost right after leaving my car.
Other popular short hikes include Akaka Falls Trail on the Big Island and the Mānoa Falls Trail on Oahu.
These paths usually have good signs and safe walkways, so I can focus on the nature around me.
I hear birds and sometimes see tropical flowers and ferns, which makes the walk more fun.
When I hike near waterfalls, I wear sturdy shoes because the ground can get muddy and slick.
Early morning is often the best time for rainbow viewing since the sunlight hits the spray at the right angle.
Staying Safe: Flash Floods and Weather
Hawaii’s weather can change fast, so I always check the local forecast before I start hiking.
Heavy rain can happen with little warning, especially in the mountains and near streams, and can lead to dangerous flash floods.
If the sky gets dark or rain starts, I head back right away.
Trails through valleys are the most risky during storms because water can rise fast.
I avoid crossing running streams and never climb on wet rocks near the top of a waterfall.
I carry a rain jacket and a small first-aid kit in my backpack.
Many trailheads have warning signs about flash floods—when I see these, I pay close attention.
I also let someone know where I’m going in case of an emergency.
Popular Viewing Areas in Nature
I find the best spots for rainbow viewing where waterfalls, good sunlight, and clear views come together.
Rainbow Falls in Hilo usually shows amazing rainbows in the mist on sunny mornings.
Early visits let me enjoy quiet nature before crowds arrive.
Besides Rainbow Falls, I like Akaka Falls State Park and the lookout at Waimea Canyon on Kauai.
These places have easy trails and safe viewing platforms with big, open sky.
Sometimes I see double rainbows when rain and sun come together at just the right time.
Nature spots with native plants and flowers make the experience peaceful.
When I pick areas with tall trees and clean water, I often see native birds, butterflies, and other unique Hawaiian wildlife while waiting for the next rainbow.
Cultural and Mythological Significance of Rainbows
Rainbows are a big part of Hawaiian culture, history, and beliefs.
Learning about their meaning makes seeing them in Hawaii more special.
Rainbows in Hawaiian Culture
Rainbows are common in Hawaii and carry deep cultural meaning.
In Hawaiian traditions, a rainbow is more than a pattern of light; it stands for hope, unity, and the promise of positive change.
In daily life, rainbows remind people to stay hopeful, even during hard times.
Rainbows also appear on Hawaii’s license plates and in local treats like rainbow shave ice.
This shows how important rainbows are in Hawaiian life.
Sometimes, rainbows mark special places or moments, making them sacred and worthy of respect.
They also stand for inclusivity and diversity.
Many in Hawaii see rainbows as a sign of acceptance, which connects with the local value of aloha—a spirit of love, peace, and kindness.

The Legend of Goddess Hina
In Hawaiian mythology, Goddess Hina is a powerful and respected figure.
Hina is often linked with the moon and with rainbows, both symbols of beauty and mystery.
The stories say that rainbows serve as bridges between the earth and the divine or between people and the gods.
One famous legend says Hina used a rainbow to travel between worlds.
She gives guidance, protection, and inspiration.
When a rainbow appears, some Hawaiians believe Hina is watching over her people.
These stories about Hina have passed down through generations.
They help connect today’s Hawaiian culture with its ancient roots.
Waianuenue and Hawaiian Mythology
Waiānuenue, or Rainbow Falls, is a famous spot in Hilo, Hawaii.
According to Hawaiian mythology, this waterfall is home to rainbows and spiritual power.
When I visit, I often see rainbows stretch across the mist, creating a magical view.
Waiānuenue connects to stories of Hina as well.
The legend says her home was a cave behind the waterfall.
People believe the rainbow weaving through the mist shows her presence and blessing.
This site is still special for Hawaiian ceremonies and celebrations.
Waiānuenue brings together natural landmarks, mythology, and Hawaiian culture.

Tips for Capturing Rainbows
I find that rainbow viewing in Hawaii is best with a little planning.
It’s important to have my camera ready, know where double rainbows might appear, and be aware of how rare moonbows can be.
Photography Advice and Camera Settings
I always set my camera to capture fast-changing light.
For sharp rainbow photos, I use a low ISO (like 100 or 200) to avoid grain.
I set my aperture between f/8 and f/11 for clear, focused images.
Rainbows often look best just after rain, with the sun low in the sky behind me.
When I line up the shot, I make sure the sun is at my back and the landscape adds something interesting, like palm trees or waterfalls.
I follow the rule of thirds for balanced photos.
I avoid harsh midday sunlight because rainbows show up better in the early morning or late afternoon.
If I’m using my phone, I tap to focus on the rainbow and adjust the exposure to avoid washed-out colors.
A polarizing filter can make the rainbow’s colors brighter.
I try not to miss the moment, as rainbows can fade quickly.
For more tips on camera settings and composition, I refer to these photography guidelines.
Best Places for Double Rainbows
Hawaii is famous for double rainbows, and I’ve had the most luck spotting them during the rainy winter season when quick showers pass and the sun comes out right after.
Open spaces with a wide view of the sky help me see both arches.
Some great places I visit are valleys, large beaches, and overlooks on islands like Oahu or Maui.
In the morning, I’ve captured bright double arcs at locations such as the North Shore and Hana Highway.
I always check weather patterns before heading out.
Light rain and sun together, especially near waterfalls or green mountains, can create dramatic double rainbows.
The state’s unique climate makes it possible to catch these rare sights in many locations.
For more location advice, I often check guides on where to find the best rainbows in Hawaii.
Chasing Moonbows at Night
Moonbows, or nighttime rainbows, happen when moonlight shines through rain.
These are much less common than daytime rainbows, but I can sometimes spot them near waterfalls or open fields on clear nights with a bright full moon.
I look for places with little artificial light, like Rainbow Falls on the Big Island.
Setting my camera on a tripod is a must for longer exposures, usually between 10 and 30 seconds, so I capture enough light for the faint rainbow to appear.
The best chance for moonbows is about two days before or after a full moon, when the moon is bright and high in the sky.
Patience helps, since these rainbows are often dim to the naked eye but appear clearly in photos.
To learn more about the best time to see a moonbow at Rainbow Falls, I sometimes check this local guide.
Practical Considerations for Rainbow Seekers
Before I head out to search for Hawaii’s famous rainbows, I always check where to go, how to stay safe, and how to make the most of my trip.
By planning ahead, I can enjoy the scenic beauty of nature and improve my chances of seeing a rainbow.
Accessibility of Viewing Areas
Getting to the best rainbow viewing spots in Hawaii matters to me.
Some popular places, like Rainbow Falls in Hilo and Hawaii Volcanoes National Park, are easy to reach by car and have nearby parking.
These spots usually have paved paths or short walks from the parking area.
Some remote locations, like hidden waterfalls or mountain lookouts, may require hiking.
Trails can be muddy or uneven, so I always check if they are suitable for my comfort and ability.
For those with limited mobility, I choose locations with accessible paths or lookout points.
Many parks and sites list their accessibility details online.
I check these in advance, especially if I am with family or friends who need smooth walkways or ramps.
Staying Safe in Nature
While enjoying nature, I always make safety my top priority.
Hawaii’s weather can change quickly, and rain often makes trails slippery.
I wear sturdy shoes with good grip and bring a rain jacket.
If I get caught in a sudden shower, I watch my step and avoid climbing wet rocks, as they can be very slippery.
I keep an eye out for posted signs or warnings, especially near cliffs, waterfalls, or fast-moving water.
To stay safe, I also bring water, snacks, and sun protection.
Cell phone coverage can be spotty in some areas, so I tell someone where I am going if I plan to hike alone.
Planning Your Visit
When I plan my rainbow outing, I check the weather forecast and pick days with both sunshine and showers.
I usually have the best luck in the early morning or late afternoon during Hawaii’s rainy season, which is winter.
Rainbows appear most often at these times because the sun sits lower in the sky.
For more tips about the best season and timing, I read expert advice at ActivityAuthority and Spectrum News.
I always bring my camera or phone to capture the moment.
I keep extra batteries and memory cards with me, especially if I plan to stay out for a while.
If I arrive early, I find fewer people around, which makes it easier to enjoy the view and take photos.
Booking flights and places to stay in advance helps me save money and find spots close to rainbow hotspots.
If I don’t rent a car, I look for tours or shuttles that visit popular viewing locations.
