When the heat sits

Normal highs reach 90°F from May 24 through September 21, covering 121 dates. The broader mild season, normal highs of 70°F or more, runs February 19 to November 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.

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 42°F around January 4.

Where the wet dates fall

The likeliest wet date is March 10, when 22% of years recorded at least a hundredth of an inch. The driest is August 2 at 12%. Summed across the calendar, that is about 72 wet dates a year.

The widest day

January 31 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where San Antonio Stinson Stands Nationally

Summers here run among the most heat-heavy normals calendars in the country: on about 121 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.

Days and nights track unusually close together; the widest normal swing, about 23°F, is narrower than most stations record.

San Antonio Stinson earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

San Antonio Stinson 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 Stinson has no dry season to plan around, though it does carry a 33.1°F seasonal spread.

The gap between the wettest and driest month still matters: May averages 3.9" and February 1.6". The three wettest months together take 34% 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 Stinson, it arrives in quantity

29.7" of precipitation falls across only about 72 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

How San Antonio Stinson's climate pattern fits together

cooling led · moderate · mid swing

Air-conditioning demand is the clearest thermal signal here. San Antonio Stinson accumulates 3,474 cooling degree days, more than twice its 1,241 heating total; the monthly table shows when that imbalance builds rather than treating it as a year-round condition.

San Antonio Stinson's 29.7 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.

August and January mark the typical warm and cold ends of the calendar in San Antonio Stinson's middle-range seasonal profile. The measured spread is 33.1°F. The annual average is 71°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

The frost-free window extends for about 286 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 San Antonio Stinson'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 San Antonio Stinson that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from San Antonio Stinson's primary station: SAN ANTONIO STINSON AP (USW00012970). For informational purposes only.

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 Stinson; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
