The year, day by day
The year in Jacksonville runs from a mild 43°F around January 11 to 92°F at the peak near July 16, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 16 through August 26, covering 72 dates. The broader mild season, normal highs of 70°F or more, runs February 21 to November 30.
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.
No freezing date
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 43°F around January 11.
Where the wet dates fall
The likeliest wet date is August 15, when 48% of years recorded at least a hundredth of an inch. The driest is April 26 at 20%. Summed across the calendar, that is about 114 wet dates a year.
The widest day
March 18 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Where Jacksonville Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 72 days a year, more than four out of five ranked stations record.
The normal water year runs well above the national norm at roughly 53 inches.
Jacksonville earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Jacksonville runs a summer-peaked wet season
40% of Jacksonville'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 7.6", on an unusually narrow 28.3°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.
- Wettest three months: June, September, August, taking 41% of the annual total between them.
- Driest month: November at 2.0".
- Winter share: 17% falls in December, January and February.
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.
When it rains in Jacksonville, it arrives in quantity
53.4" of precipitation falls across only about 114 wet days here, averaging 0.47 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 114 a year, 31% of all days
- Average depth per wet day
- 0.47 inches
- Most wet days
- August, about 15
- Fewest wet days
- April, about 6
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.
Jacksonville's record shows no measurable snowfall
This station measured snowfall across the 1991-2020 period and recorded none: the annual normal is 0.0 inches. That is a measured zero rather than missing data, which is a meaningful distinction here , most stations in the database simply do not report snow at all, and those pages say nothing about it.
A thirty-year normal of zero describes the typical year at this station. It is not a claim that snow has never fallen in the area.

Data-derived climate profile
How Jacksonville's climate pattern fits together
cooling led · wet · low swing
Warm-season load persists through a relatively even calendar in Jacksonville. Cooling totals 2,803 degree days, more than double the 1,228 heating measure, and the 28.3°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 Jacksonville. Recorded annual snowfall is negligible. The month-by-month bars distinguish a concentrated wet season from moisture spread across the calendar.
Jacksonville's 28.3°F seasonal spread is compact even though precipitation is abundant. July and January mark the typical warm and cold ends of the calendar. The annual average is 69°F. Temperature is relatively steady; the monthly rows show how rain and snow observations vary across the calendar.
The frost-free window extends for about 285 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
These labels group NOAA 1991-2020 normals from Jacksonville's primary station, so the summer figures are a thirty-year average rather than a ceiling: individual years have run hotter and will again. For Jacksonville that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.
