Maui weather in short
The National Weather Service in Honolulu describes two seasons: a "summer" from May to October and a "winter" from October to April. The strongest rain comes with winter storms between October and April. Northeast trade winds blow most of the time, but in winter fronts, cyclones and Kona storms can interrupt them.
The sea stays warm all year. It is coolest at 73 to 74°F (23°C) in late February and March and warmest at nearly 80°F (27°C) in late September and early October. The figures below are NOAA normals for 1991 to 2020. They are averages, not forecasts, so check the daily forecast before you go.

| Winter storms | October to April | The strongest rain falls in these months, brought by winter storms. |
Hurricane season 2026
The central Pacific season runs from 1 June to 30 November. For 2026 NOAA expected a 70 percent chance of an above-normal season, with 5 to 13 tropical storms against an average of 4 to 5, and named El Niño as the reason. By 14 October 2026 it had counted 6 named storms, 5 hurricanes and 3 major hurricanes.
Several storms passed south of the islands. Local press reported that Hurricane Nolo in late September left thousands of households in West Maui and Upcountry without power. Flights can be disrupted statewide when a storm passes, so take travel insurance, keep your plans flexible and follow the National Weather Service forecast. Rain can also close roads, and the Road to Hāna is the first place to check.
