The year, day by day
Keiser works both ends of the calendar. Normal highs climb to 91°F by July 5 and hold at or above 90°F on 65 dates, then normal lows drop to freezing or below on 40 dates, bottoming at 30°F around January 16.
When the heat sits
Normal highs reach 90°F from June 19 through August 22, covering 65 dates. The broader mild season, normal highs of 70°F or more, runs April 10 to October 26.
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.
The freezing stretch
The normal low stays at or below 32°F into February 5, then returns to freezing around December 28, covering 40 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
Where the wet dates fall
The likeliest wet date is May 2, when 34% of years recorded at least a hundredth of an inch. The driest is August 27 at 21%. Summed across the calendar, that is about 107 wet dates a year.
The widest day
October 9 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Where Keiser Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 65 days a year, more than four out of five ranked stations record.
The normal water year runs well above the national norm at roughly 52 inches.

Keiser spreads its precipitation across the year
Neither half of the year dominates here: June through August take 21% of the annual total and December through February 26%, with neither reaching the 35% that would mark a distinct wet season. Keiser has no dry season to plan around, though it does carry a 43.1°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 5.5" and August 3.0". The three wettest months together take 31% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.
When it rains in Keiser, it arrives in quantity
52.2" of precipitation falls across only about 107 wet days here, averaging 0.49 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 107 a year, 29% of all days
- Average depth per wet day
- 0.49 inches
- Most wet days
- March, about 11
- Fewest wet days
- August, about 7
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.
Snow reaches Keiser, but rarely amounts to much
The normals record 1.8 inches of snow a year here, most likely in February. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 1 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Keiser's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Keiser averages 52.2 inches of precipitation a year. Annual snowfall totals 1.8 inches. The monthly table supplies the seasonal distribution hidden by that annual total.
July and January mark the typical warm and cold ends of the calendar in Keiser's middle-range seasonal profile. The measured spread is 43.1°F. The annual average is 62°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Keiser's normal, at 3,357 and 2,133 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
A roughly 228-day frost-free season sits inside this mixed heating-and-cooling profile. Start and end dates matter because both sides of the thermostat register during a normal year.
These labels group NOAA 1991-2020 normals from Keiser's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Keiser, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
