One island, many different weather patterns.
Maui is made up of numerous sub-climates. Weather can change considerably between the coast, valleys, windward slopes, upcountry communities, and the summit of Haleakalā.
General patterns change from one part of the island to another.
The island of Maui is made up of numerous different sub-climates. Depending on where you are, the weather can act in a multitude of ways. For the most part, each area has a general weather pattern.
Below we've listed the weather that each part of the island typically holds.
Windward moisture
Moist ocean air rises along mountain slopes, cools, and produces more rainfall.
Leeward sunshine
Areas sheltered from the prevailing moisture tend to be warmer, sunnier, and drier.
Elevation changes
Higher elevations can be much cooler and wetter than nearby coastal communities.
Explore Maui weather by region.
Select a region to read the original weather guidance provided on the My Maui weather page.
Because of the warm ocean airflow, the West Maui Mountains get a lot of rain. The Iao Valley rarely sees a day without some kind of precipitation. Wailuku Town is located over here as well as some of Upper West Maui like Honolua Bay. All of these areas are lush and green due to the near-constant wet weather. If it is raining, check out things to do on a rainy day under our Activities and Attractions.
Regional guidance is not a live forecast.
Maui weather can change quickly across short distances. Review the current forecast before leaving for Hana, driving into the mountains, visiting upcountry, or traveling to Haleakalā Summit.
Conditions at the summit can be dramatically colder than conditions near the coast. Bring warmer clothing and verify road, cloud, wind, and precipitation conditions before departure.
Prepare for changing conditions.
Use this optional checklist before traveling between Maui’s coastal, mountain, windward, and summit environments.
