Regional context
Parkesburg's baseline climate, derived from NOAA NCEI 1991-2020 normals at the nearest reporting station, swings from a January mean of 30°F to a July mean of 75°F — a 45°F seasonal arc typical of the mid-latitude bands. Annual precipitation runs about 52.1 inches spread across roughly 81 days with measurable rain or snow each year.
Rainfall stays relatively even across the calendar: September tops out at 5.2 inches across 6.9 days with measurable rain, and February settles around 3.3 inches across 6.1 rainy days — a comparatively narrow seasonal range. That even-rainfall rhythm puts Parkesburg alongside places like Pomeroy, PA, Sadsburyville, PA and Atglen, PA — places without a single dominant storm season, where moisture arrives steadily across the calendar.
The frost-sensitive growing window opens around mid-April, when overnight lows reliably clear freezing for cool-season crops like peas, lettuce, spinach, and radishes. Heat-loving transplants like tomatoes, peppers, and squash generally hold off for another 10-14 days to clear the last spring frost risk window. The window closes around mid-November, when overnight lows resume dipping below freezing and frost-tender plants need protection or harvest. The dates above are 1991-2020 normals; in a given year either bookend can move 1-2 weeks either direction. Within Parkesburg, low-lying parcels along drainage features typically lose 4-7°F of overnight low temperature versus the bench positions on calm clear nights, which shifts the working last-frost date by a week or more.
