Growing Degree Days in Indiana
Indiana has accumulated about 1663 GDD so far this year (base 50°F, since January 1), averaged across 1 NOAA USCRN station. Through July 1, 2026.
How to Read This Number
Growing degree days count accumulated heat: 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, plant growth regulator reapplication, and grub control. Treat it as a timing signal read against a model, not a fixed date. The total here is measured air temperature from NOAA USCRN stations, base 50°F, accumulated from January 1 — state the model whenever you compare totals, because a different base or start date is not interchangeable.

Growing Degree Days FAQ for Indiana
How many growing degree days has Indiana accumulated this year?
Indiana has accumulated about 1663 growing degree days (base 50°F, since January 1), averaged across 1 NOAA USCRN station. The total climbs through summer and levels off as temperatures fall.
What base temperature and start date are these totals?
These are base 50°F growing degree days accumulated from January 1, the turf-industry convention. Each day adds the amount its average air temperature runs above 50°F, floored at zero. Totals from a different base or start date are not interchangeable, so the model is stated explicitly wherever a number appears.
What are growing degree days used for in lawn care?
Turf managers track the running total to time temperature-driven tasks: crabgrass pre-emergent before germination, annual bluegrass seedhead suppression, plant growth regulator reapplication, and grub control. Growing degree days are a timing signal read against a model, not a fixed calendar date.
