The year, day by day
The year in Auburn runs from a mild 37°F around December 20 to 94°F at the peak near July 23, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 30 through August 31, covering 63 dates. The broader mild season, normal highs of 70°F or more, runs April 24 to November 1.
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 February 9, when 37% of years recorded at least a hundredth of an inch. The driest is July 25 at 1%. Summed across the calendar, that is about 68 wet dates a year.
The widest day
August 3 carries the biggest normal gap between afternoon and dawn, 30°F between the normal high and the normal low.

Where Auburn Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 63 days a year, more than four out of five ranked stations record.
Auburn earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Auburn's wet season runs through the cold months
December, January and February carry 56% of the year's precipitation here, while June through August contribute 1%. 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 31.6°F seasonal spread.

- January, 7.0"
- Driest month
- July, 0.0"
- Wettest three months
- January, December, February (56% 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 Auburn, it arrives in quantity
36.1" of precipitation falls across only about 67 wet days here, averaging 0.54 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 67 a year, 18% of all days
- Average depth per wet day

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 Auburn's climate pattern fits together
mixed demand · moderate · mid swing
July and December mark the typical warm and cold ends of the calendar in Auburn's middle-range seasonal profile. The measured spread is 31.6°F. The annual average is 61°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Auburn's normal, at 2,813 and 1,453 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 283 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.
Auburn's 36.1 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 Auburn'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 Auburn, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
