The year, day by day
The year in San Manuel runs from a mild 46°F around January 10 to 99°F at the peak near July 31, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from May 11 through October 16, covering 159 dates. The broader mild season, normal highs of 70°F or more, runs January 1 to December 31.
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 46°F around January 10.
The widest day
October 30 carries the biggest normal gap between afternoon and dawn, 28°F between the normal high and the normal low.

Where San Manuel Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 159 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
San Manuel earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
San Manuel spreads its precipitation across the year
Neither half of the year dominates here: June through August take 28% of the annual total and December through February 11%, with neither reaching the 35% that would mark a distinct wet season. San Manuel has no dry season to plan around, though it does carry an unusually narrow 27.9°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 5.1" and February 0.8". The three wettest months together take 43% 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.

Data-derived climate profile
How San Manuel's climate pattern fits together
cooling led · moderate · low swing
Warm-season load persists through a relatively even calendar in San Manuel. Cooling totals 4,133 degree days, more than double the 720 heating measure, and the 27.9°F seasonal range is compact rather than sharply divided.
San Manuel's 22.9 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
Temperature varies within a narrow 27.9°F band across the normal year. August and January mark the typical warm and cold ends of the calendar. The annual average is 74°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.
A frost-free growing-season length is not available for San Manuel. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
These labels group NOAA 1991-2020 normals from San Manuel's primary station, so the summer figures are a thirty-year average rather than a ceiling: individual years have run hotter and will again. For San Manuel that means a descriptive range only — not an official NOAA classification and not a prediction for next summer.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from San Manuel's primary station: SAN MANUEL (USC00417981). For informational purposes only.
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 San Manuel; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for San Manuel comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
