Growing Degree Days by ZIP Code and State
The average growing-degree-day total across the US so far this year is 3722 GDD (base 50°F, accumulated since January 1), measured at 123 NOAA USCRN stations. Growing degree days count the heat a lawn has banked: each day adds the amount its average temperature runs above 50°F, the point where cool-season growth and most pests get going. Turf managers use the running total to time crabgrass pre-emergent, annual bluegrass seedhead suppression, and grub control. Every total here is measured, not modeled.
