Zones / 9b

Zone 9b

In the 2023 PRISM ZIP table, zone 9b is labeled with an average annual extreme minimum of 25°F to 30°F. 2,085 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 2 to April 2. That is a range across stations, not a zone-wide frost normal. USDA does not publish a single frost date per half-zone.
