What is each month like in Yuba City?
NOAA's grid estimates the normals every 5 km or so from the stations around each point, terrain included. It smooths between stations, so night lows at the heart of a large city can run warmer than the grid shows: at five big-city airports we compared, the grid's highs were within about 1°F of the station and its lows 1-6°F cooler. The nearest record's high and low are beside each month.

How much snow, how late a frost, what zone and how much sun in Yuba City?
NOAA's grid gives no snow, frost dates or records, so these come from the nearest station record, Marysville (4 miles SE, 62 ft). NOAA publishes no snowfall normal for it; the nearest record that has one, Colusa (21 miles W), gets 0 inches a year. The last spring frost (32°F) comes after February 11 in half of years and the first autumn frost before November 30. Its record high is 115°F (2022) and its record low 19°F (2012) (kept since 2000).
The USDA's 2023 Plant Hardiness Zone Map puts Yuba City in zone 9b (ZIP code 95991).
Over a year 87% of the sunlight that would reach the ground under clear skies gets through the clouds in the area (5.1 kWh per square metre a day, NASA POWER 2001-2020); July is the sunniest month (98%) and December the cloudiest (69%).
Marysville's page has its months, frost probabilities, records by month and recent years. NOAA's grid has monthly figures only, so there are no day-by-day month pages for Yuba City; the nearest record's month pages have them.
