Maui typically experiences a transition from summer to fall during September. This period offers warm temperatures, lower humidity than the summer months, and generally calmer ocean conditions. Average daytime highs range from the low to mid-80s Fahrenheit (high 20s to low 30s Celsius), while nighttime lows typically dip into the low 70s Fahrenheit (low 20s Celsius). Rainfall is relatively low, contributing to sunny days ideal for outdoor activities.
Understanding Maui’s climate during this month is crucial for planning a successful trip. The pleasant conditions make it a popular time for visitors seeking a balance between warm weather and fewer crowds compared to the peak summer season. Historically, September has marked the beginning of the “shoulder season” in Maui, offering potential cost savings on accommodations and flights. This period allows travelers to enjoy the island’s natural beauty, from its beaches and volcanic landscapes to its diverse marine life, under favorable weather conditions.
