The freeze dates behind the calendar

The guide gives windows, not frost dates. These are the NOAA medians for every station Pima County ZIP codes cite. They run from the desert floor up to the mountains and their freeze dates differ widely, while the guide gives the whole county one set of dates.

Freeze dates and summer heat — the 18 NOAA stations Pima County ZIP codes cite, 1991–2020 normals (median dates)

Where the Tucson-area dates come from

University of Arizona Cooperative Extension, Pima County Master Gardeners, Pima County Planting Guide (Pima County Vegetable Planting and Harvesting Guide), file dated January 2025. It lists 66 crops in 24 half-month planting windows; S means sow seeds, T transplant, and S/T either.

Guide (PDF): https://www.extension.arizona.edu/sites/default/files/2025-01/Pima-County-Vegetable-Planting-and-Harvesting-Guide-Adobe-PDF-1.pdf

⚠️ It is written for Pima County, which holds every one of the 50 ZIP codes in the Tucson, AZ metro area. It is not written for the Phoenix area, which has its own Maricopa County calendar, nor for Yavapai County, and it gives one set of dates for the whole county, high ground included. The guide's grid was read by eye from the PDF. It also shades harvest periods; that shading was not transcribed, so this site shows when to plant, not when to harvest.
