The year, day by day
The year in Sherman runs from a mild 34°F around January 9 to 94°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 June 27 through August 30, covering 65 dates. The broader mild season, normal highs of 70°F or more, runs April 2 to October 29.
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 34°F around January 9.
Where the wet dates fall
The likeliest wet date is May 17, when 28% of years recorded at least a hundredth of an inch. The driest is July 19 at 16%. Summed across the calendar, that is about 79 wet dates a year.
The widest day
March 26 carries the biggest normal gap between afternoon and dawn, 21°F between the normal high and the normal low.

Where Sherman Stands Nationally
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 21°F.
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 65 days a year, more than four out of five ranked stations record.

Sherman spreads its precipitation across the year
Neither half of the year dominates here: June through August take 23% of the annual total and December through February 20%, with neither reaching the 35% that would mark a distinct wet season. Sherman has no dry season to plan around, though it does carry a 39.8°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 5.5" and January 2.5". The three wettest months together take 34% 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 Sherman, it arrives in quantity
44.3" of precipitation falls across only about 79 wet days here, averaging 0.56 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 79 a year, 22% of all days
- Average depth per wet day
- 0.56 inches
- Most wet days
- May, about 9

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 Sherman's climate pattern fits together
mixed demand · moderate · mid swing
July and January mark the typical warm and cold ends of the calendar in Sherman's middle-range seasonal profile. The measured spread is 39.8°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 Sherman's normal, at 2,727 and 2,261 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.
The frost-free window extends for about 250 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
Sherman's 44.3 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 Sherman'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 Sherman, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
