Regional context

Per NOAA NCEI 1991-2020 normals, Red Hill runs from a 45°F January mean to 80°F in July, a 35°F seasonal spread, with near 53.6 inches of precipitation across about 179 wet days.

Red Hill's rain peaks in summer: September brings 6.8 inches over 23.0 thunderstorm-fed days, while November sees just 3.1 inches across 10.0 days under cooler, drier air. That puts Red Hill in a summer-convective cohort with places like Forestbrook, SC, Conway, SC and Carolina Forest, SC.

Once Red Hill passes mid-March, overnight freezes fade and peas, lettuce, spinach, and radishes can be sown. Red Hill's heat-lovers — tomatoes, peppers, squash — hold off until Red Hill's frost risk clears, 10-14 days on. The season ends by mid-December in Red Hill, once hard frosts set back in. Red Hill's low ground holds frost later into spring than Red Hill's benches, which run 3-5 days ahead.
