The year, day by day
The year in Marysville Yuba County runs from a mild 38°F around December 17 to 97°F at the peak near July 16, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 16 through September 15, covering 92 dates. The broader mild season, normal highs of 70°F or more, runs April 8 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 38°F around December 17.
Where the wet dates fall
The likeliest wet date is December 20, when 36% of years recorded at least a hundredth of an inch. The driest is July 24 at 1%. Summed across the calendar, that is about 64 wet dates a year.
The widest day
July 16 carries the biggest normal gap between afternoon and dawn, 36°F between the normal high and the normal low.

Where Marysville Yuba County Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 92 days a year, more than four out of five ranked stations record.
Daily temperature swings run wider than most of the country, peaking near 36°F between the normal high and low.
Marysville Yuba County earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Marysville Yuba County'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 2%. 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 31.9°F seasonal spread.
- Wettest month
- January, 3.8"
- 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.
How Marysville Yuba County's precipitation splits across the calendar
About 63 days a year record measurable precipitation here, carrying 20.1" between them, or roughly 0.32 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.

Data-derived climate profile
How Marysville Yuba County's climate pattern fits together
mixed demand · moderate · mid swing
July and December mark the typical warm and cold ends of the calendar in Marysville Yuba County's middle-range seasonal profile. The measured spread is 31.9°F. The annual average is 62°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Marysville Yuba County's normal, at 2,551 and 1,499 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 292 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.
Marysville Yuba County's 20.1 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 Marysville Yuba County'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 Marysville Yuba County, 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 Marysville Yuba County; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
