May marks the beginning of Hawaii’s summer season, bringing warmer daytime temperatures and generally drier weather. North shore waves often ease, expanding options for swimming and snorkeling, while early May can provide a window between spring break travel and peak summer vacations.
Which Hawaiian Island Is Best To Visit in May?
Oahu is the best Hawaiian island to visit in May because it combines excellent beaches and first-time attractions with two meaningful annual events: Lei Day celebrates Hawaiian artistry and aloha, while the Memorial Day lantern-floating ceremony offers a powerful moment of remembrance.
1. Oahu: Best for Lei Day & Memorial Day Traditions
May begins with Hawaii’s Lei Day, celebrated annually on May 1. Honolulu’s official celebration at Kapi'olani Park features lei displays and competitions, hula, music, workshops and Hawaiian cultural traditions. The event is held rain or shine.
Later in the month, Shinnyo Lantern Floating Hawaii takes place on Memorial Day at Ala Moana Beach. Candle-lit lanterns are set on the water during a ceremony centered on remembrance, gratitude and aloha.
Between events, enjoy Waikiki Beach, hike Diamond Head or explore Pearl Harbor and 'Iolani Palace. Royal Caribbean shore excursions from Honolulu include historical tours, snorkeling, scenic drives and Hawaiian cultural experiences.
2. Kaua'i: Best for Calmer Water & Green Scenery
Kaua'i combines lingering spring greenery with the beginning of calmer ocean conditions. Travelers can explore Waimea Canyon, kayak the Wailua River or follow scenic roads toward waterfalls and Nāpali Coast viewpoints. As winter swells subside, some north shore beaches and boat routes may become more accessible.
May is also well suited to botanical gardens and mālama experiences such as approved cleanups or native planting projects.
3. Maui: Best for Beaches & Scenic Drives
Maui is a great May choice for travelers who want warm beach days and plenty of outdoor variety. Relax near Kāʻanapali or Wailea, drive through the rainforest toward Hāna or visit Haleakalā National Park.
Summer conditions generally bring gentler water to many north-facing shores, although currents and wind can still change quickly. Travelers hoping to see humpback whales should know that the season is ending, and sightings are far less common than in winter.
Sunrise entry at Haleakalā requires advance reservations, and the summit remains considerably cooler than the coast — even as sea-level temperatures rise.
4. Island of Hawaii: Best for Sunshine & Volcanic Landscapes
The Island of Hawaii, often called the Big Island, offers warm May adventures across beaches, lava fields, coffee country and cloud forests. Kailua-Kona’s leeward location generally provides drier weather for snorkeling and coastal sightseeing.
Visit Kealakekua Bay, tour a Kona coffee and cacao farm or explore historical landmarks near the waterfront. Inland adventures reach Kohala waterfalls, the Kona Cloud Forest and Hawaii Volcanoes National Park. Check official updates before entering active volcanic areas.
Royal Caribbean excursions from Kailua-Kona include snorkeling, farm tours, waterfall adventures, submarine trips, cultural landmarks and volcano-focused experiences.
Is May a Good Time To Visit Hawaii?
Yes, May is a good time to visit Hawaii for warmer weather, swimming, snorkeling, hiking and seasonal traditions. Early and mid-May may feel calmer than peak summer, while Memorial Day weekend can draw additional crowds.
Hawaii’s summer runs from May through October, with average daytime temperatures near 85°F (29°C) at sea level and nights roughly 10°F cooler. Leeward coasts are generally drier than windward areas.
