The year, day by day
The year in San Antonio Incarnate Word runs from a mild 40°F around January 1 to 96°F at the peak near August 7, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 3 through September 13, covering 103 dates. The broader mild season, normal highs of 70°F or more, runs February 28 to November 19.
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 40°F around January 1.
Where the wet dates fall
The likeliest wet date is February 9, when 32% of years recorded at least a hundredth of an inch. The driest is August 6 at 14%. Summed across the calendar, that is about 89 wet dates a year.
The widest day
February 13 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Where San Antonio Incarnate Word Stands Nationally
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.
San Antonio Incarnate Word earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

San Antonio Incarnate Word 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. San Antonio Incarnate Word has no dry season to plan around, though it does carry a 33°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 4.4" and February 1.9". The three wettest months together take 36% 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 San Antonio Incarnate Word, it arrives in quantity
34.0" of precipitation falls across only about 89 wet days here, averaging 0.38 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 89 a year, 24% of all days
- Average depth per wet day
- 0.38 inches
- Most wet days
- February, about 10
- Fewest wet days
- August, about 4
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 San Antonio Incarnate Word, 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; about 0 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 San Antonio Incarnate Word's climate pattern fits together
mixed demand · moderate · mid swing
August and January mark the typical warm and cold ends of the calendar in San Antonio Incarnate Word's middle-range seasonal profile. The measured spread is 33.0°F. The annual average is 69°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in San Antonio Incarnate Word's normal, at 1,527 and 2,995 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 276 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.
San Antonio Incarnate Word's 34.0 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 San Antonio Incarnate Word'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 San Antonio Incarnate Word, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

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. No exact Gazetteer row for San Antonio Incarnate Word; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
