The year, day by day
Sonora works both ends of the calendar. Normal highs climb to 97°F by August 2 and hold at or above 90°F on 109 dates, then normal lows drop to freezing or below on 49 dates, bottoming at 30°F around January 1.
When the heat sits
Normal highs reach 90°F from May 26 through September 11, covering 109 dates. The broader mild season, normal highs of 70°F or more, runs March 5 to November 14.
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 31, then returns to freezing around December 14, covering 49 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 29, when 16% of years recorded at least a hundredth of an inch. The driest is January 1 at 10%. Summed across the calendar, that is about 49 wet dates a year.
The widest day
February 9 carries the biggest normal gap between afternoon and dawn, 32°F between the normal high and the normal low.

Where Sonora Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 109 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Sonora earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Sonora spreads its precipitation across the year
Neither half of the year dominates here: June through August take 33% of the annual total and December through February 13%, with neither reaching the 35% that would mark a distinct wet season. Sonora has no dry season to plan around, though it does carry a 37.7°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 3.2" and December 0.7". The three wettest months together take 37% 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.
When it rains in Sonora, it arrives in quantity
22.7" of precipitation falls across only about 49 wet days here, averaging 0.47 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 49 a year, 13% of all days
- Average depth per wet day
- 0.47 inches
- Most wet days
- October, about 5

A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.

Data-derived climate profile
How Sonora's climate pattern fits together
mixed demand · moderate · mid swing
July and January mark the typical warm and cold ends of the calendar in Sonora's middle-range seasonal profile. The measured spread is 37.7°F. The annual average is 66°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Sonora's normal, at 2,263 and 2,567 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 219-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.
Sonora's 22.7 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.
These labels group NOAA 1991-2020 normals from Sonora'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 Sonora, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
