The current average 2-inch soil temperature across South Carolina is 83°F. Readings range from 82°F to 84°F, from 3 USDA and NOAA monitoring stations. Soil across South Carolina is running 6°F above the seasonal normal of 77°F for mid-September, based on 3 of 3 stations with historical records. South Carolina spans USDA hardiness zones 8a to 9b, crossing from cool-season into warm-season grass country. Last updated September 14, 2026.
Soil across South Carolina is cooling off its summer peak at an average of 83°F at 2 inches. The fall poa annua pre-emergent window is in play as readings fall through the 65–70°F band, and cool-season overseeding follows close behind.
For warm-season lawns (bermuda, zoysia, St. Augustine), the best time to plant grass seed in South Carolina is late spring into early summer, when soil is warming and a full growing season lies ahead. The window opens when 2-inch soil reaches 65°F and keeps rising, and closes as soil cools back through 65°F, typically around October 18.

Fall is when broadleaf herbicide works hardest.
Apply fall pre-emergent when 2-inch soil falls back through 70°F and keeps declining; that crossing is when poa annua and winter annual weeds sprout.
Bermuda and zoysia go tan in winter.
Check whether your soil is warm enough for the seed you bought: cool-season grass seeds into 50-65°F soil (tall fescue prefers 60°F and up), warm-season into 75-85°F.
The current average 2-inch soil temperature across South Carolina is 83°F. Readings range from 82°F to 84°F depending on location and elevation, from 3 USDA and NOAA monitoring stations. Soil across South Carolina is running 6°F above the seasonal normal of 77°F for mid-September, based on 3 of 3 stations with historical records.
Apply pre-emergent herbicide when soil at 2 inches reaches 55°F for several consecutive days. Timing varies across South Carolina, so check your city's page for station-specific readings and the pre-emergent timing recommendation.
South Carolina spans USDA hardiness zones 8a to 9b, crossing from cool-season into warm-season grass country. For warm-season grasses (bermuda, zoysia), the window typically opens around April 14, based on historical 2-inch soil temperature averages at 4 in-state stations. Timing varies by location, so check your city's planting window for the dates specific to your area.
