Where these dates come from

NOAA weather station BARSTOW DAGGETT AP, CA US (USW00023161), 1991–2020 climate normals. It's the nearest station for 5 zip codes, all within 33 miles:

92310, 92327, 92338, 92365, 92398

2 of these zip codes are more than 30 miles from the station, so their real frost dates may differ by a week or more.

Planting dates follow common university extension advice; your local extension service can fine-tune them for your soil and microclimate.
