Maui, the second-largest Hawaiian island, experiences distinct microclimates due to its varied terrain, from volcanic peaks to coastal plains. March typically marks the transition from the wetter winter months to the drier summer season. Average temperatures range from the high 60s to the low 80s Fahrenheit (low 20s to high 20s Celsius). Rainfall decreases compared to the preceding months, yet brief showers remain possible, particularly in the windward areas. Ocean conditions generally favor swimming, snorkeling, and other water activities, with water temperatures averaging in the mid-70s Fahrenheit (low 20s Celsius).
Understanding Maui’s climatic conditions during March is essential for planning a successful trip. This period offers a balance between pleasant temperatures and relatively lower rainfall, creating favorable conditions for outdoor activities like hiking, whale watching (as the humpback whale migration season winds down), and exploring the island’s diverse landscapes. Historically, March has been a popular time for visitors seeking a taste of Hawaiian paradise before the peak summer crowds arrive.
