Arizona's 20 largest cities (U.S. Census Bureau 2025 estimates), A to Z, each with its nearest NOAA station and the distance to it. Search any town to get its nearest station. "Plant tender crops from" is halfway between the average last frost and the date frost is over 9 years in 10; if frost is in the forecast after it, wait until it passes and nights stay above 36°F.

Planting windows from Arizona's Cooperative Extension Service. Filter by season or crop group; every view has its own link.
Each crop has its own link, like #tomatoes. Tender crops wait for the frost dates above; succession crops are sown again every few weeks for a steady harvest.

§ 040 · Questions
Questions about planting in Arizona
When is the last frost in Arizona?
On average from about January 5 in Lake Havasu City to June 4 in Flagstaff. Frost is over 9 years in 10 by February 19 to July 1.
When can I plant tomatoes in Arizona?
The extension service lists January to June. Tomatoes are frost-tender, so Ezina dates them from about February 4 in Phoenix. If frost is in the forecast, wait until it passes.
What can I plant in Arizona in October?
The extension calendar lists artichokes, asparagus, beets, bok choy, broccoli, brussels sprouts and more for October.
Is it too late for a fall garden?
The latest fall windows on the calendar close in December. Filter by Fall above to see what is still open.
Why not use my USDA zone?
A zone is the coldest winter night, not a frost date. These dates come from NOAA station records and the extension service.
Can Ezina date plantings for my address?
Yes. Run Ezina Dig on your address and your bed plans are dated from that site's own frost records, on iPhone and Android in the contiguous U.S.
