Weather factors to check
- Wind-driven wildfire risk in dry leeward grasslands
- Freezing temperatures and high winds atop Haleakala
Air Quality
Maui Air Quality App
Air quality is part of everyday weather planning, especially for workouts, commuting, wildfire smoke, heat, and sensitive groups. A local forecast should make that context easy to act on in Maui.
Local Air Quality Answer
Quick answer for Maui air quality
Air quality planning in Maui works best when weather context is included, because heat, humidity, wind, smoke, dust, and stagnant air can change outdoor risk quickly.
When conditions can shift
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.
Best planning uses
- Comparing windward and leeward beach forecasts
- Checking Haleakala summit conditions before sunrise trips
- Watching flash flood alerts along the Hana Highway
- Tracking winter surf and marine warnings
Air quality changes how weather feels
For Maui, temperature, humidity, wind, and air quality together determine whether outdoor plans feel comfortable or risky.

Local Weather Context for 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.

Radar and Alert Context
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.
