The year, day by day

Sonoita works both ends of the calendar. Normal highs climb to 92°F by June 20 and hold at or above 90°F on 33 dates, then normal lows drop to freezing or below on 13 dates, bottoming at 32°F around December 25.

When the heat sits

Normal highs reach 90°F from June 7 through July 9, covering 33 dates. The broader mild season, normal highs of 70°F or more, runs March 23 to November 12.

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 January 1, then returns to freezing around December 20, covering 13 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.

The widest day

June 3 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Data-derived climate profile

How Sonoita's climate pattern fits together

mixed demand · mid swing

July and December mark the typical warm and cold ends of the calendar in Sonoita's middle-range seasonal profile. The measured spread is 30.6°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 Sonoita's normal, at 2,639 and 1,407 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 238-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.

A moisture-range label is withheld because Sonoita's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.

These labels group NOAA 1991-2020 normals from Sonoita'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 Sonoita, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Questions about Sonoita's climate

How many days above 90°F does Sonoita get?
Sonoita averages about 60 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Sonoita?
Sonoita has 2,639 heating degree days and 1,407 cooling degree days annually, a fairly balanced heating/cooling split. Degree-day definitions: reading weather data.

Data Sources

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Sonoita's primary station: SONOITA (USC00027990). 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 0468220), not an incorporated municipality. Match rule for Sonoita: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
