September marks the transition from summer to fall on the Hawaiian island of Maui. This period typically offers a blend of summer-like conditions with slightly decreased humidity and rainfall compared to the preceding months. Ocean temperatures remain warm, conducive to swimming and various water activities. Visitors can expect average high temperatures in the mid-80s Fahrenheit (around 29-30 degrees Celsius) with slightly cooler evenings.
Understanding the typical climate at this time of year is beneficial for planning a trip. It allows travelers to pack appropriately, anticipate potential weather variations, and choose activities best suited to the conditions. Historically, September has represented a desirable time to visit due to the pleasant balance of warmth and lower visitor numbers compared to peak summer months. This can lead to a more relaxed experience with potentially better availability for accommodations and activities.
