December on this Gulf Coast barrier island offers a respite from the mainland’s colder temperatures. Expect daytime highs typically ranging from the high 60s to low 70s Fahrenheit (around 20-22 degrees Celsius), with nighttime lows averaging in the 50s Fahrenheit (around 10-15 degrees Celsius). Sunshine is abundant, and rainfall is minimal, creating generally dry and pleasant conditions. Water temperatures remain comfortable enough for wading and some water activities, though a wetsuit might be preferable for extended exposure.
The mild climate during this period makes it an attractive destination for those seeking a warm winter escape. The reduced crowds compared to peak season allow for a more relaxed experience of the island’s natural beauty, including its pristine beaches and diverse wildlife. Historically, December has marked the beginning of the island’s transition into its dry season, providing favorable conditions for fishing and other outdoor pursuits.
