Frequently asked questions

What does zone 6A mean?

Zone 6A is a USDA plant hardiness band based on average annual extreme minimum winter temperature. It helps compare winter-cold exposure across places; it is not a planting prescription.

Why is the table sorted by population?

Population ordering surfaces larger communities first. The zone total counts all published ZIPs in band 6A; page through the table to browse beyond the first page.

Is a hardiness zone the same as a climate normal?

Hardiness zones summarize winter extreme cold. ZIP pages on US5 also show precipitation, snow, and FEMA risk context separately.
