The year, day by day
The year in Boerne runs from a mild 36°F around January 5 to 95°F at the peak near August 6, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 15 through September 9, covering 87 dates. The broader mild season, normal highs of 70°F or more, runs March 9 to November 15.
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 36°F around January 5.
Where the wet dates fall
The likeliest wet date is February 22, when 26% of years recorded at least a hundredth of an inch. The driest is August 1 at 13%. Summed across the calendar, that is about 79 wet dates a year.
The widest day
April 6 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Boerne Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 87 days a year, more than four out of five ranked stations record.

Boerne spreads its precipitation across the year
Neither half of the year dominates here: June through August take 25% of the annual total and December through February 18%, with neither reaching the 35% that would mark a distinct wet season. Boerne has no dry season to plan around, though it does carry a 33.3°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 5.3" and February 2.2". The three wettest months together take 35% 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 Boerne, it arrives in quantity
37.5" of precipitation falls across only about 79 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.

- about 79 a year, 22% of all days
- Average depth per wet day
- 0.47 inches
- Most wet days
- May, about 8
- Fewest wet days
- August, about 5
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 Boerne, but rarely amounts to much
The normals record 0.1 inches of snow a year here, most likely in December. 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.
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 Boerne's climate pattern fits together
mixed demand · moderate · mid swing
August and January mark the typical warm and cold ends of the calendar in Boerne's middle-range seasonal profile. The measured spread is 33.3°F. The annual average is 67°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Boerne's normal, at 1,916 and 2,480 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.
The frost-free window extends for about 243 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.
Boerne's 37.5 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Recorded annual snowfall is negligible. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Boerne'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 Boerne, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
