The best time to visit Maui is April to May and September to October: the island is drier, the seas are calmer on many beaches, and you miss the winter rain and the biggest holiday crowds. Come from December to April for humpback whales, and expect wetter weather from November to April.

Monthly averages 1991-2020 for Kahului Airport (NOAA). These are long-term averages, not a forecast.
Summer: about May to October
Generally drier. Calm seas on north-facing bays such as Honolua make this the best snorkeling season there, and Maui has the warmest weather of the year in August and September, with highs near 90°F. Daytime temperatures barely change across the year: highs stay between 82 and 90°F in every month.
Winter: about November to April
Generally wetter, with big surf on north-facing shores, so save Honolua and the north-shore beaches for summer and stick to south and west-side beaches such as Makena and Kaanapali for swimming. It is also humpback whale season, peaking January to March; see our Maui guide for whale-watching tours.
The summit and the Hana side behave differently
- Haleakala summit: the National Park Service says it is about 30°F cooler than the coast, from below freezing to highs of 50 to 65°F, and wind and damp clouds make it feel colder. Read Haleakala sunrise: reservations, what to wear and what to expect.
- Kipahulu and the east: hot, humid and rainy. Bring rain gear and mosquito repellent. Flash floods and rockfall can happen at any time, which matters on the Road to Hana.
- Molokini: what to know before you book.
Seasons are general guidance. Check the National Park Service Haleakala weather page and the National Weather Service Kahului forecast before you go.
