Zones / 7a

Zone 7a

In the 2023 PRISM ZIP table, zone 7a is labeled with an average annual extreme minimum of 0°F to 5°F. 4,856 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 March 29 to May 4. That is a range across stations, not a zone-wide frost normal. USDA does not publish a single frost date per half-zone.
