The year in Fort Myers SW FL Rgnl runs from a mild 54°F around January 12 to 92°F at the peak near August 15, and the normal low never reaches freezing on any date in the record.
Normal highs reach 90°F from June 5 through September 15, covering 103 dates. The broader mild season, normal highs of 70°F or more, runs January 1 to December 31.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 54°F around January 12.
The likeliest wet date is August 2, when 64% of years recorded at least a hundredth of an inch. The driest is March 1 at 21%. Summed across the calendar, that is about 132 wet dates a year.
February 22 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.
Any date's 1991–2020 normal for Fort Myers SW FL Rgnl.
Summers here run among the most heat-heavy normals calendars in the country: on about 103 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
The normal water year runs well above the national norm at roughly 53 inches.

52% of Fort Myers SW FL Rgnl's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is June at 10.3", on an unusually narrow 19°F seasonal spread. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
53.4" of precipitation falls across only about 132 wet days here, averaging 0.41 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Data-derived climate profile
cooling led · wet · low swing
Warm-season load persists through a relatively even calendar in Fort Myers SW FL Rgnl. Cooling totals 3,933 degree days, more than double the 268 heating measure, and the 19.0°F seasonal range is compact rather than sharply divided.
Warm-season demand is paired with a wet annual normal: 53.4 inches of precipitation at Fort Myers SW FL Rgnl. Snowfall is not added to the interpretation because its annual value is missing. The month-by-month bars distinguish a concentrated wet season from moisture spread across the calendar.
Fort Myers SW FL Rgnl's 19.0°F seasonal spread is compact even though precipitation is abundant. August and January mark the typical warm and cold ends of the calendar. The annual average is 75°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
A frost-free growing-season length is not available for Fort Myers SW FL Rgnl. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
These labels group NOAA 1991-2020 normals from Fort Myers SW FL Rgnl's primary station, so the summer figures are a thirty-year average rather than a ceiling: individual years have run hotter and will again. They are descriptive ranges, not an official NOAA classification or a forecast for any specific year.

Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. The reproducible method is an exact normalized name-and-state match; unresolved is an upper bound on facilities because spelling variants can be missed.
