The year, day by day
Summer here tops out rather than builds: the warmest normal high is 88°F around July 6, short of 90°F on every date, while 184 dates carry a normal low at or below freezing, the coldest 14°F near January 1.
The freezing stretch
The normal low stays at or below 32°F into April 16, then returns to freezing around October 16, covering 184 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 31, when 30% of years recorded at least a hundredth of an inch. The driest is January 15 at 9%. Summed across the calendar, that is about 55 wet dates a year.
The widest day
June 7 carries the biggest normal gap between afternoon and dawn, 39°F between the normal high and the normal low.

Where Alcalde Stands Nationally
Aridity defines the water calendar: about 11 inches in a normal year lands this among the driest tenth of ranked stations.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 39°F, sharper than nine in ten ranked stations see.

Alcalde runs a summer-peaked wet season
38% of Alcalde'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 1.8", on a 42°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 42% of the annual total between them.
- Driest month: February at 0.4".
- Winter share: 15% 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 Alcalde's precipitation splits across the calendar
About 55 days a year record measurable precipitation here, carrying 11.1" between them, or roughly 0.20 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 Alcalde, but rarely amounts to much
The normals record 10.7 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 6 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.

Scarce-water calendar
Where Alcalde's limited precipitation lands
heating led · dry · mid swing
Alcalde's energy balance leans toward cold weather: 5,785 annual heating degree days against 496 for cooling. Its 42.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 147 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and December mark the typical warm and cold ends of the calendar in Alcalde's middle-range seasonal profile. The measured spread is 42.0°F. The annual average is 50°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alcalde's cold-season load does not imply a wet climate. Annual precipitation is 11.1 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 10.7 inches. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
