City comparison
US Cities With the Highest Growing Degree Days
Frost dates tell you how long the outdoor window is. Growing degree days help explain how much heat accumulates inside that window. This ranking compares U.S. cities by base 50°F GDD, a useful reference point for warm-season crop planning.
The ranking
Cities are ranked by base 50°F growing degree day accumulation. Higher values usually mean more seasonal heat for warm-season crops, but water, heat stress, frost timing, and variety choice still matter.

What this ranking means
A city with more base 50°F GDD generally has more heat available for warm-season crops. In the hottest U.S. locations, that can also mean heat stress, drought pressure, or irrigation needs become part of the gardening picture.
Compare with US Cities With the Longest Growing Seasons and the full Growing Degree Days by City reference.
Methodology
U.S. cities are ranked by their base 50°F seasonal growing degree day reference value. Base 50°F GDD is a useful broad comparison point for warm-season crops, though individual crops may use different base temperatures.
High GDD does not guarantee crop success. Extreme heat, drought, humidity, soil temperature, irrigation, frost timing, variety choice, and local microclimates still affect real-world maturity and harvest quality.
