The year, day by day
Zion National Park works both ends of the calendar. Normal highs climb to 101°F by July 16 and hold at or above 90°F on 111 dates, then normal lows drop to freezing or below on 64 dates, bottoming at 28°F around December 21.
When the heat sits
Normal highs reach 90°F from May 31 through September 18, covering 111 dates. The broader mild season, normal highs of 70°F or more, runs March 30 to November 3.
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 2, then returns to freezing around December 1, covering 64 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 February 21, when 29% of years recorded at least a hundredth of an inch. The driest is June 17 at 8%. Summed across the calendar, that is about 66 wet dates a year.
The widest day
June 8 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Zion National Park Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 111 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 33°F between the normal high and low.

Zion National Park spreads its precipitation across the year
Neither half of the year dominates here: June through August take 19% of the annual total and December through February 35%, with neither reaching the 35% that would mark a distinct wet season. Zion National Park has no dry season to plan around, though it does carry a 44°F seasonal spread.
The gap between the wettest and driest month still matters: February averages 2.1" and June 0.2". The three wettest months together take 37% 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.
How Zion National Park's precipitation splits across the calendar
About 65 days a year record measurable precipitation here, carrying 16.3" between them, or roughly 0.25 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.
Snow reaches Zion National Park, but rarely amounts to much
The normals record 4.0 inches of snow a year here, most likely in December. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 2 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Zion National Park's climate pattern fits together
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 16.3 inches annually, within PlainClimate's dry band. Annual snowfall totals 4.0 inches. 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 Zion National Park's middle-range seasonal profile. The measured spread is 44.0°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 Zion National Park's normal, at 3,257 and 2,211 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 203-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 Zion National Park'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 Zion National Park, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

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 Zion National Park; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
