December in Maui, Hawaii, typically marks the beginning of the wetter season and the arrival of whales. Average temperatures range from highs in the low 80s Fahrenheit (high 20s Celsius) to lows in the high 60s Fahrenheit (around 20 Celsius). Ocean temperatures are typically pleasant, averaging in the mid-70s Fahrenheit (low-mid 20s Celsius). Rainfall increases compared to the drier summer months, but showers are often brief and localized, allowing for plenty of sunshine. This period also experiences increased humidity.
Understanding Maui’s December climate is essential for travelers planning winter getaways. This information allows for informed packing decisions, activity planning, and potential contingency plans should inclement weather arise. Historically, December has been a popular time for visitors seeking a respite from colder climates, drawn by the moderate temperatures and the opportunity for whale watching. The reliable trade winds of the summer months tend to weaken during this time, sometimes leading to Kona winds, which bring warmer, more humid conditions from the south.
