Maui in September by trip type

What to expect in September

🎯 Ideal beach temperature (26°C) — crowds still moderate Autumn in Maui is often underrated: 26°C, golden light and declining crowds. An interesting window. Expect rain on 37% of days — a light raincoat in the bag is recommended. A good balance between weather and crowds, even if July (8.5/10) remains theoretically better.
