Zone 11a
In the 2023 PRISM ZIP table, zone 11a is labeled with an average annual extreme minimum of 40°F to 45°F. 197 ZIP codes carry that half-zone. USDA’s map page describes these bands as 5°F half-zones inside 10°F zones.
Among cities on this site in this half-zone, the median last 32°F date at each city’s station runs from January 9 to January 24. That is a range across stations, not a zone-wide frost normal. USDA does not publish a single frost date per half-zone.
