Alerts to prioritize
- Flash flooding in valleys and along the Hana Highway
- Winter high surf on north- and west-facing shores
- Wind-driven wildfire risk in dry leeward grasslands
- Freezing temperatures and high winds atop Haleakala
Local Alerts
Useful alerts are specific, timely, and tuned to the places you care about. For Maui, that means notifications should help you act before weather disrupts your day.
Local Alert Answer
Weather alerts around Maui should be specific enough to separate routine forecast changes from conditions that need action. Winter Kona storms and high-surf episodes, the June-November hurricane season, and any trade-wind breakdown are the periods when Maui forecasts need island-specific attention.
Radar and alerts read very differently across the island because the mountains split weather into windward and leeward regimes; one coast can flood while another stays bone dry.
A strong Maui weather alerts app should separate routine forecast changes from conditions that require action, like severe storms, hazardous heat, poor air quality, or disruptive wind and rain.
WeatherAI is built around location-aware planning, so alerts can support commutes, travel, outdoor events, and recurring routines around Maui.
Maui has large climate contrasts between its coasts, windward slopes, and high elevations, so no single station describes the whole island. At Kahului Airport, the 1991-2020 reference averages range from a daily high of 82°F (28°C) in Jan to 90°F (32°C) in Sep. Monthly precipitation averages sum to 16.2 inches (412 mm) per year.
Hawaii has two seasons: kau (summer, May-October) with steady trade winds and dry leeward coasts, and hooilo (winter, November-April) when Kona lows can bring island-wide rain and powerful surf to north-facing shores. Central Pacific hurricane season runs June through November, and while direct hits are rare, systems like Lane in 2018 have brought flooding rain and damaging winds to Maui. The Haleakala summit occasionally sees ice and even snow in winter.
