Grants's normals sit in a dry climate class: BSk
Precipitation is low relative to temperature but above true desert thresholds: cold semi-arid steppe (BSk). Class BSk is the Peel et al. (2007) label for this station's monthly mean temperature and precipitation normals: dry (arid or semi-arid), specifically cold semi-arid steppe.

The year, day by day
Grants works both ends of the calendar. Normal highs climb to 93°F by June 30 and hold at or above 90°F on 56 dates, then normal lows drop to freezing or below on 190 dates, bottoming at 13°F around December 19.
When the heat sits
Normal highs reach 90°F from June 13 through August 7, covering 56 dates. The broader mild season, normal highs of 70°F or more, runs April 14 to October 24.
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 April 21, then returns to freezing around October 15, covering 190 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 August 3, when 32% of years recorded at least a hundredth of an inch. The driest is May 31 at 10%. Summed across the calendar, that is about 57 wet dates a year.
The widest day
June 7 carries the biggest normal gap between afternoon and dawn, 44°F between the normal high and the normal low.

Where Grants Stands Nationally
Aridity defines the water calendar: about 10 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 44°F, sharper than nine in ten ranked stations see.

Grants runs a summer-peaked wet season
41% of Grants'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 41.6°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 49% of the annual total between them.
- Driest month: February at 0.4".
- Winter share: 16% 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.
Grants is dry, and what does fall arrives gently
Only about 57 days a year record measurable precipitation here, 16% of the calendar, and they carry 9.7" between them. At roughly 0.17 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.
The wettest month by count is August at about 10 wet days; the driest is June at about 3.
A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.
Snow reaches Grants, but rarely amounts to much
The normals record 7.9 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 5 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 Grants's limited precipitation lands
heating led · dry · mid swing
Grants's energy balance leans toward cold weather: 5,359 annual heating degree days against 681 for cooling. Its 41.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 139 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 Grants's middle-range seasonal profile. The measured spread is 41.6°F. The annual average is 52°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Grants's cold-season load does not imply a wet climate. Annual precipitation is 9.7 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 7.9 inches. The snowfall and rainfall fields should be read separately rather than inferred from temperature.
