The year, day by day
The year in Hesperia runs from a mild 35°F around December 17 to 97°F at the peak near July 29, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 9 through September 20, covering 104 dates. The broader mild season, normal highs of 70°F or more, runs March 19 to November 10.
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.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 35°F around December 17.
The widest day
June 17 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Hesperia Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 104 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Aridity defines the water calendar: about 8 inches in a normal year lands this among the driest tenth of ranked stations.
Hesperia earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Hesperia's wet season runs through the cold months
December, January and February carry 55% of the year's precipitation here, while June through August contribute 6%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a 33.9°F seasonal spread.

Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.

Scarce-water calendar
Where Hesperia's limited precipitation lands
mixed demand · dry · mid swing
Local precipitation is sparse in this otherwise mixed profile. The station reports 7.8 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.
August and December mark the typical warm and cold ends of the calendar in Hesperia's middle-range seasonal profile. The measured spread is 33.9°F. The annual average is 64°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Hesperia's normal, at 2,414 and 1,924 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.
Hesperia has a long frost-free window of roughly 276 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.
