Hana in May: Lei Day, Waterfalls, Warm Seas and Rain on the Windward Side

On the first of May, Hana’s little ballpark and church lawns fill with fresh lei of maile, plumeria and ti leaf, and the neighbors who made them hand them around as if it were nothing. Above the bay, the hills have reached their deepest green, while ginger and wild hibiscus border the road in, and the afternoons remain gentle and drawn out. May is a good month for a slow stay in this far corner of East Maui, for people who come for the rainforest, the black sand and the pace of a town with one main road.

What is the weather like in Hana in May?

Warm, green and showery: May in Hana is comfortable in a T-shirt all day, with passing rain that comes off the trade winds and rarely lasts.

Hana sits on the windward side of Maui, so clouds pile up against the slopes of Haleakala and drop their rain here before the dry resorts of Wailea and Kihei ever see them. Expect a shower or two a day, often in the early morning or at night, followed by sun and rainbows. The waterfalls and pools along the road keep their flow, and trails can be muddy.

Evenings are mild enough to sit outside in a light layer, and the ocean feels pleasantly warm without being bathwater. Conditions along this shoreline change daily, sometimes moving from early hours to later in the day, so check the posted notices along with that day’s waves and currents prior to entering, and only go in near a lifeguard where one is stationed. Summer swells tend to be gentler on many shores than in winter, but that never means a beach is calm.

What to do in Hana in May

May in Hana is about being outdoors in the green: a festival day at the start of the month, waterfalls at full voice, and lunch from a roadside stand. Nothing here is rushed.

Lei Day and the spirit of May

Lei Day falls on May 1 throughout Hawaii, and in a place as close-knit as Hana, it lands as heartfelt, not staged. Schools and churches put out lei, children carry flowers, and you will see hula and music in the open air. Look for a community event or a school program on the day rather than a big show.

The tradition is about giving, so a lei here usually carries a story: who picked the flowers, which tree they came from. If someone offers you one, accept it with a smile and a mahalo. The rest of the month keeps the same easy mood, with Memorial Day weekend at the end bringing families to the beaches and picnic tables.

Waterfalls, pools and black sand

May rain keeps the streams full, so the waterfalls along the Hana Highway, such as Twin Falls and Wailua Falls, look their best. Further on, the Kipahulu district of Haleakala National Park, with the Oheo Gulch pools stepping down toward the sea, is a place to walk, look and listen to the water. Rain upstream can change a stream quickly, so follow park signs and rangers’ guidance.

Closer to town, Waianapanapa State Park has a black sand beach, sea caves and a coastal trail through hala trees. Every person who visits Waianapanapa State Park must book a time slot ahead of time. Hamoa Beach, a crescent of pale sand below cliffs, is where many people spend an afternoon. Both are best early, before the day-trippers from the other side of the island arrive, and the surf varies by day.

Hana Bay is a good quiet stop for watching local families fish and paddle. Kahanu Garden, with its breadfruit collection and the great stone temple of Piilanihale, is a calm place to walk. Treat the stones with respect and do not climb on them.

Fruit stands, plate lunches and slow meals

Eating in Hana is simple and good. Banana bread is sold at stands all along the road, along with fruit, coconut candy and fresh juices, and the stalls are usually staffed by neighbors who will tell you what is ripe. Shave ice and a plate lunch with rice, greens and grilled fish or kalua pork are the standard fuel for a day of waterfalls.

Restaurants in town are few, so plan your meals around the day rather than hoping to find a table anywhere. Bring a cooler for the drive, and keep an appetite for the evening, when the town gets quiet and the stars come out over the bay.

Is Hana busy in May?

Moderately: May is lighter than the winter holidays and the heart of summer, but the road to Hana is never empty.

The mainland spring break rush has faded by then, and families with school-age children mostly wait for summer. You will see couples, hikers and travelers combining Hana with a wider Maui trip, plus the day-trip traffic that fills the best waterfall stops in late morning. Memorial Day weekend at the end of the month brings more locals and visitors to the beaches.

Lodging in Hana is limited, with a few small inns, cottages and vacation rentals, so rooms can still disappear on busy weekends. Weekdays are quieter, and restaurants and stands are easy to manage if you go early. Staying overnight rather than racing back puts you on the road in the calm hours.

What to pack for Hana in May

Pack for warm days, quick showers and muddy trails, and leave the heavy layers at home.

• A light rain jacket that packs small, for the showers that blow in off the slopes
• Sturdy sandals or water shoes with grip for wet rocks and trail mud
• Mineral sunscreen with zinc oxide or titanium dioxide, the only kind sold in Maui County without a prescription since October 1, 2022
• A swimsuit, a quick-dry towel and a dry bag for the car
• A small cooler and a refillable water bottle for the drive

Good to know before you go

May falls just before the Central Pacific hurricane season, which runs from June 1 to November 30, so the month is outside the official season. Rain is the more everyday concern here, since showers can change road and trail conditions in an afternoon. Hana is a small, remote community, so treat it with the courtesy you would show any village: park only where it is allowed, leave the reef and wildlife alone, and respect the places that are sacred to Native Hawaiians.

Is May a good time to visit Hana?

Yes, for travelers who want green hills, flowing waterfalls and a warm sea, and who do not mind frequent showers in the plan.

Compared with April, May is a touch warmer and a little wetter, and the sea has crept up a notch. June feels hotter and has slightly less rain, but it also begins the official hurricane season and the busy family weeks. May sits comfortably in between, with more room on the road and a gentle pace in town. What sets May apart in Hana is the way it begins: a day of lei and neighbors, then weeks of ripe fruit stands, brimming streams and long soft evenings over the bay.
