The year, day by day
The year in Tohono Chul runs from a mild 36°F around January 1 to 103°F at the peak near June 23, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from May 12 through October 8, covering 150 dates. The broader mild season, normal highs of 70°F or more, runs February 19 to November 30.
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 1.
The widest day
April 4 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where Tohono Chul Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 150 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Daily temperature swings run wider than most of the country, peaking near 35°F between the normal high and low.
Tohono Chul earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Data-derived climate profile
How Tohono Chul's climate pattern fits together
cooling led · mid swing
Air-conditioning demand is the clearest thermal signal here. Tohono Chul accumulates 3,151 cooling degree days, more than twice its 1,546 heating total; the monthly table shows when that imbalance builds rather than treating it as a year-round condition.
A moisture-range label is withheld because Tohono Chul's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
July and January mark the typical warm and cold ends of the calendar in Tohono Chul's middle-range seasonal profile. The measured spread is 36.0°F. The annual average is 69°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
The frost-free window extends for about 281 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 Tohono Chul'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 Tohono Chul 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 Tohono Chul's primary station: TOHONO CHUL (USC00028590). 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 Tohono Chul; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Tohono Chul comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
