Fresno, California frost dates
Frost is uncommon in Fresno. NOAA's 1991–2020 normals give a 50% chance of a 32°F freeze after January 14 and before December 14. In practice that means a freeze in roughly half of winters or fewer, usually on just a night or two, so dates are a poor guide here. Gardeners here plan around heat and the cool season, not frost.
