The year, day by day
The year in Redding Muni runs from a mild 37°F around December 20 to 101°F at the peak near July 20, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 11 through September 23, covering 105 dates. The broader mild season, normal highs of 70°F or more, runs April 10 to November 3.
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 37°F around December 20.
Where the wet dates fall
The likeliest wet date is December 13, when 40% of years recorded at least a hundredth of an inch. The driest is July 27 at 2%. Summed across the calendar, that is about 81 wet dates a year.
The widest day
September 2 carries the biggest normal gap between afternoon and dawn, 35°F between the normal high and the normal low.

Where Redding Muni Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 105 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Daily temperature swings run wider than most of the country, peaking near 35°F between the normal high and low.

Redding Muni's wet season runs through the cold months
December, January and February carry 53% of the year's precipitation here, while June through August contribute 3%. 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 36.8°F seasonal spread.
- Wettest month
- December, 6.3"
- Driest month
- July, 0.1"
- Wettest three months
- December, January, February (53% of the year)
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.
When it rains in Redding Muni, it arrives in quantity
33.5" of precipitation falls across only about 81 wet days here, averaging 0.42 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 81 a year, 22% of all days
- Average depth per wet day
- 0.42 inches
- Most wet days
- December, about 13
- Fewest wet days
- July, about 1
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.
Snow reaches Redding Muni, but rarely amounts to much
The normals record 2.6 inches of snow a year here, most likely in January. 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 1 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.

Data-derived climate profile
How Redding Muni's climate pattern fits together
mixed demand · moderate · mid swing
July and December mark the typical warm and cold ends of the calendar in Redding Muni's middle-range seasonal profile. The measured spread is 36.8°F. The annual average is 63°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Redding Muni's normal, at 2,576 and 2,032 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 263 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.
Redding Muni's 33.5 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Annual snowfall totals 2.6 inches. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Redding Muni'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 Redding Muni, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

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 Redding Muni; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
