The year, day by day
Ozona works both ends of the calendar. Normal highs climb to 95°F by July 28 and hold at or above 90°F on 105 dates, then normal lows drop to freezing or below on 56 dates, bottoming at 30°F around January 6.
When the heat sits
Normal highs reach 90°F from May 29 through September 10, covering 105 dates. The broader mild season, normal highs of 70°F or more, runs March 12 to November 7.
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 12, covering 56 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 August 24, when 14% of years recorded at least a hundredth of an inch. The driest is November 25 at 8%. Summed across the calendar, that is about 40 wet dates a year.
The widest day
February 2 carries the biggest normal gap between afternoon and dawn, 31°F between the normal high and the normal low.

Where Ozona Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 105 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.

Ozona 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 13%, with neither reaching the 35% that would mark a distinct wet season. Ozona has no dry season to plan around, though it does carry a 37.5°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 2.8" and December 0.8". 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 Ozona, it arrives in quantity
19.8" of precipitation falls across only about 39 wet days here, averaging 0.50 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 39 a year, 11% of all days
- Average depth per wet day
- 0.50 inches
- Most 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.

Data-derived climate profile
How Ozona's climate pattern fits together
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 19.8 inches annually, within PlainClimate's dry band. Snowfall is not added to the interpretation because its annual value is missing. The monthly distribution matters because the total alone does not reveal the timing.
July and January mark the typical warm and cold ends of the calendar in Ozona's middle-range seasonal profile. The measured spread is 37.5°F. The annual average is 65°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Ozona's normal, at 2,485 and 2,367 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 230-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 Ozona'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 Ozona, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Ozona's primary station: OZONA (USC00416734). 2 NOAA stations are mapped to the Ozona area; the primary station's record is used for consistency. For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as a census-designated place (GEOID 4854552), not an incorporated municipality. Match rule for Ozona: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Ozona comes from its primary NOAA station record.
