The year, day by day
Alpine works both ends of the calendar. Normal highs climb to 93°F by June 13 and hold at or above 90°F on 81 dates, then normal lows drop to freezing or below on 47 dates, bottoming at 31°F around January 1.
When the heat sits
Normal highs reach 90°F from May 27 through August 15, covering 81 dates. The broader mild season, normal highs of 70°F or more, runs March 11 to November 11.
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 30, then returns to freezing around December 15, covering 47 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 July 29, when 33% of years recorded at least a hundredth of an inch. The driest is March 6 at 8%. Summed across the calendar, that is about 65 wet dates a year.
The widest day
April 14 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Alpine Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 81 days a year, more than four out of five ranked stations record.
Daily temperature swings run wider than most of the country, peaking near 33°F between the normal high and low.

Alpine runs a summer-peaked wet season
52% of Alpine'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 August at 3.0", on a 31.6°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: August, July, September, taking 52% of the annual total between them.
- Driest month: March at 0.4".
- Winter share: 9% 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.
How Alpine's precipitation splits across the calendar
About 65 days a year record measurable precipitation here, carrying 16.1" 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 Alpine, but rarely amounts to much
The normals record 2.2 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 1 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 Alpine's climate pattern fits together
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 16.1 inches annually, within PlainClimate's dry band. Annual snowfall totals 2.2 inches. The monthly distribution matters because the total alone does not reveal the timing.
June and January mark the typical warm and cold ends of the calendar in Alpine's middle-range seasonal profile. The measured spread is 31.6°F. The annual average is 63°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Alpine's normal, at 2,467 and 1,688 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 215-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 Alpine'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 Alpine, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
