Maui's Climate: Warm, Not Scorching—Thanks to Trade Winds
Maui enjoys a tropical climate with warm, stable temperatures year-round—rarely "very hot" in the uncomfortable sense.
Temperature Profile
- Average highs: 78–88°F (26–31°C) at sea level.
- Average lows: 63–72°F (17–22°C).
- Summer (May–Oct): Warmest, more humid; highs ~85–88°F.
- Winter (Nov–Apr): Slightly cooler, drier; highs ~78–82°F.
Why It's Not "Too Hot"
- Trade winds: Persistent northeast breezes (10–20 mph) provide natural cooling.
- Ocean moderation: Water temps 74–80°F buffer extremes.
- Low humidity (relatively): Compared to tropics like Florida or Southeast Asia.
Microclimates Matter
- Leeward (west/south) – Kihei, Lahaina, Wailea: Sunny, dry, warmest.
- Windward (north/east) – Haiku, Hana: Wetter, cooler, lush.
- Upcountry (Makawao, Kula, Haleakalā): 1,500–7,000 ft; 10–20°F cooler; can be chilly at night.
- Summit (Haleakalā, 10,023 ft): Near freezing; snow rare but possible.
Heat Index & Comfort
Heat index rarely exceeds 95°F. UV index is extreme (10–11+) year-round—sunscreen essential. Hurricane season: June–Nov (peak Aug–Oct); direct hits rare but possible.
Maui is "warm paradise," not "scorching heat"—ideal for most visitors.
