The year, day by day
The year in Saguaro National Park runs from a mild 40°F around December 19 to 102°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 14 through October 1, covering 141 dates. The broader mild season, normal highs of 70°F or more, runs March 1 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 40°F around December 19.
The widest day
May 29 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Where Saguaro National Park Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 141 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Saguaro National Park earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Data-derived climate profile
How Saguaro National Park's climate pattern fits together
cooling led · mid swing
Air-conditioning demand is the clearest thermal signal here. Saguaro National Park accumulates 3,262 cooling degree days, more than twice its 1,399 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 Saguaro National Park'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 December mark the typical warm and cold ends of the calendar in Saguaro National Park's middle-range seasonal profile. The measured spread is 34.2°F. The annual average is 70°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
The frost-free window extends for about 324 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 Saguaro National Park'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 Saguaro National Park 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 Saguaro National Park's primary station: SAGUARO NP (USC00027398). 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 Saguaro National Park; 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 Saguaro National Park 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.
