Cities are ranked by frost-free days. This is a season-length ranking, not a full crop-success ranking — GDD, water, heat stress, and crop heat needs still matter.

What this ranking means
A longer frost-free season usually gives gardeners more room for succession planting and long-maturing crops, but it does not always mean the most comfortable or productive growing conditions. Heat stress, drought, humidity, and seasonal GDD still matter.
Compare with US Cities With the Highest Growing Degree Days and the full Frost Dates by City reference.
Methodology
U.S. cities are ranked by frost-free days between the typical last spring frost and first fall frost. Ties use base-50 GDD as a secondary signal where available.
A longer frost-free season does not always mean better conditions for every crop. High heat, humidity, drought, cool marine influence, and local microclimates can all affect real-world garden performance.
