Climate Guide
Plan your perfect Marco Island vacation with our complete weather and seasonal guide.
Marco Island enjoys a subtropical climate — warm winters, hot summers, and a distinct dry season (November–April) that draws snowbirds from across North America. Average annual temperatures hover around 76°F, and the Gulf water stays swimmable all year, dipping only to around 65°F in January and February.
The dry season (November–April) is peak time for a reason: clear skies, low humidity, and perfect beach weather. The summer rainy season brings afternoon thunderstorms but also the lowest rates and fewest crowds.
