What to Wear in Fort Myers in December
December in Fort Myers is warm and sunny, with highs averaging 77°F and mild nights near 57°F — the city's dry season is fully underway, with only about 5 rainy days and reliable sunshine most of the month. Light casual layers are all that's needed for walking the Caloosahatchee Riverwalk or the beaches on Sanibel and Fort Myers Beach; a light cardigan covers the occasional evening chill. This is the peak of Southwest Florida's visitor season for good reason.
Fort Myers in December is the beginning of the city's golden season — the summer's oppressive heat and afternoon thunderstorms have given way to dry, sunny days in the upper 70s and mild evenings near 57°F. The Caloosahatchee Riverwalk, the Edison and Ford Winter Estates, and the barrier island beaches of Sanibel and Captiva are all fully accessible without the UV intensity and humidity of summer. About 5 rainy days fall in December, typically as brief Gulf-moisture showers rather than the sustained thunderstorms of the wet season. The local style tendency runs warm-weather resort throughout the year, and December is no exception: sundresses, lightweight linen, shorts, and sandals dominate during the day, while a light cardigan or denim jacket comes out for evening dining along Patio de Leon in downtown Fort Myers. Visitors from colder climates arrive over-packed — a few warm-weather versatile pieces go considerably further than heavy layers that will stay in the suitcase all week.

Frequently Asked Questions
What should I wear in Fort Myers in December?+
Light warm-weather clothing is ideal — sundresses, linen tops, shorts, or light jeans for daytime at the Edison and Ford Winter Estates or the Sanibel beaches. A light cardigan, light sweater, or denim jacket handles the 57°F evenings along the Caloosahatchee Riverwalk or downtown Fort Myers's outdoor dining. Leave the heavy coat at home — Fort Myers's December high of 77°F makes it unnecessary.
Is December a good time to visit Fort Myers?+
December is Fort Myers's peak visitor season and deservedly so. The weather is warm without summer's heat and humidity, the shelling on Sanibel is excellent in the calmer winter surf, and the Edison and Ford Winter Estates are a genuinely distinctive historical experience. The region fills with snowbirds from November through April, so accommodations book quickly and prices reflect the season's popularity. Book early, especially for Sanibel beach properties.
What shoes are best for Fort Myers in December?+
Sandals handle the Sanibel and Fort Myers Beach sand and the Caloosahatchee Riverwalk's paved path with ease. For the Edison and Ford Winter Estates' grounds and the shell mound trails at Mound Key, a comfortable pair of walking sandals or lightweight sneakers provides more support than flip-flops on uneven terrain. A slightly dressier sandal or casual loafer works for downtown Fort Myers's restaurant scene along Patio de Leon.
How warm does it get in Fort Myers in December?+
Daytime highs average 77°F — warm enough for swimming in the Gulf of Mexico, which maintains water temperatures around 72°F through December. Overnight lows average 57°F, dropping to the low 50s during occasional cold front passages from the north. These cold snaps are brief — typically 1–2 days — before the Gulf influence returns and temperatures recover. About 5 days bring some measurable rain.
What should I pack for Fort Myers in December?+
Pack warm-weather clothing: sundresses, shorts, swimwear, light tops, and sandals cover most of what Fort Myers December demands. Add one light sweater or cardigan for evenings and air-conditioned interiors. Sunscreen is essential — the UV index stays elevated even as temperatures are more comfortable than summer. A compact rain jacket covers the occasional brief shower. Shelling gear (a mesh bag and water shoes) is worth packing for Sanibel visits.
