Owning a Car in Grass Valley

36Days a Year at 90°F or Hotter
61Nights a Year at or Below Freezing
53Inches of Rain a Year

1.38Cars per Household

68%Drive to Work Alone

Summers here bring about 36 days at 90°F or hotter. That is enough to finish off a tired battery or a weak AC compressor, so get both checked in spring rather than on the first hot day.

Lows drop to freezing on about 61 nights a year. Cold is when a weak battery finally fails, because a cold engine takes more power to turn over.

About 53 inches of rain fall in a year. Worn tires lose grip on wet roads well before they look bald, and streaky wipers are a cheap fix worth doing before the wet season, not during it.

The average commute in Grass Valley is 17 minutes each way, and 68% of workers drive there alone. 13% of households have no car at all, which is part of why mechanics who come to you do well here.
