January typically marks the middle of the wet season on Maui. Average temperatures range from highs in the low 80s Fahrenheit (high 20s Celsius) to lows in the mid-60s Fahrenheit (high teens Celsius). Rainfall is more frequent than in the summer months, and visitors should be prepared for occasional showers, particularly in the typically wetter windward areas. Ocean conditions can be rougher during this time, impacting water activities.
Understanding the prevailing climatic conditions during this period is essential for planning a trip. Packing appropriately with layers and rain gear ensures comfort. Awareness of potential weather impacts on outdoor activities, such as hiking or whale watching tours, allows for informed scheduling and alternative arrangements. Historically, January has been a popular time to visit Maui, coinciding with the peak of humpback whale season in Hawaiian waters.
