The year, day by day
Catalina State Park works both ends of the calendar. Normal highs climb to 102°F by June 22 and hold at or above 90°F on 143 dates, then normal lows drop to freezing or below on 74 dates, bottoming at 30°F around December 20.
When the heat sits
Normal highs reach 90°F from May 15 through October 4, covering 143 dates. The broader mild season, normal highs of 70°F or more, runs February 28 to November 28.
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 16, then returns to freezing around December 5, covering 74 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 6 carries the biggest normal gap between afternoon and dawn, 44°F between the normal high and the normal low.

Where Catalina State Park Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 143 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 44°F, sharper than nine in ten ranked stations see.
Catalina State Park earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Catalina State Park runs a summer-peaked wet season
42% of Catalina State Park's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is July at 2.6", on a 36.5°F seasonal spread. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: July, August, January, taking 49% of the annual total between them.
- Driest month: May at 0.2".
- Winter share: 28% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.

Scarce-water calendar
Where Catalina State Park's limited precipitation lands
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 13.2 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 December mark the typical warm and cold ends of the calendar in Catalina State Park's middle-range seasonal profile. The measured spread is 36.5°F. The annual average is 66°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Catalina State Park's normal, at 2,180 and 2,445 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 223-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.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Catalina State Park's primary station: CATALINA SP (USC00021357). 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 Catalina State 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 Catalina State Park comes from its primary NOAA station record.
