Climate & Weather in Fort Myers
Fort Myers has a tropical, subtropical Gulf Coast climate: warm winters, hot and humid summers, and a rainy season heavily concentrated in the warmer months. That warmth is a major relocation draw, paired with a real and unavoidable hurricane season.

Long-term averages for the Fort Myers/Southwest Florida International Airport (RSW) area put the coolest month, January, at an average of about 64.6°F, while the warmest month, August, averages around 83.6°F -- consistent with NOAA's 1991-2020 Climate Normals period. Frost is essentially not a concern in a typical winter, a significant part of the area's draw for snowbirds and relocating retirees.
A pronounced wet season
Fort Myers receives roughly 53 inches of rain annually on average, per long-term station data for the RSW area. The period from June through September is, by a wide margin, the wettest stretch of the year, bringing frequent afternoon thunderstorms; winters and springs are comparatively dry by contrast. New residents accustomed to more evenly distributed rainfall elsewhere should expect a genuinely different, front-loaded wet-season pattern here.
Hurricane season overlaps the wet season
Atlantic hurricane season runs June through November, with the highest-risk window from August through October -- overlapping directly with the wettest months of the year. See the flood-hurricane-risk topic for storm-specific risk, Hurricane Ian context, and insurance implications.
