Frost risk by date in Studio City
In the 55% of winters that bring a 32°F night, half of springs at Burbank Valley Pump Plt, CA see their last 32°F night by January 2; only one in ten is past it by December 11, and one in ten still has one after January 31. Counting the winters with no freeze at all, the risk of a 32°F night after January 31 is under 5% and after January 2 27%. The 29 days between the even-odds date and the one-in-ten date is narrower than at 52% of the 220 California stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.
In fall the first 32°F night comes by December 26 in half of years, as early as December 5 one year in ten, and holds off past January 18 one year in ten. A hard freeze of 28°F is less common: it came in 3% of winters. The freeze-free season lasts 364 days in a typical year, the longest of the 219 California stations; it reaches 365 days one year in ten and falls short of 330 one year in ten. On average 1 nights a year drop to 32°F or below. Nights of 36°F, when frost can still settle on leaves in low, open spots, continue 34 days longer, to about February 5, and return around December 12. No night reached 24°F in 1991–2020.
