Regional context
Cheyney University'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 50.9 inches spread across roughly 79 days with measurable rain or snow each year.
Rainfall stays relatively even across the calendar: September tops out at 5.7 inches across 6.1 days with measurable rain, and February settles around 3.1 inches across 5.5 rainy days — a comparatively narrow seasonal range. The temperate, evenly-distributed pattern groups Cheyney University with places like Dilworthtown, PA, Chester Heights, PA and West Chester, PA, where seasonal storm tracks deliver moisture more uniformly than the continental interior.
The frost-sensitive growing window opens around mid-April, when overnight lows reliably clear freezing for cool-season crops like kale, peas, spinach, and parsnips. Warm-season transplants — tomatoes, peppers, and basil — typically wait two weeks past that date to avoid late spring cold snaps. The window closes around mid-November, when overnight lows resume dipping below freezing and frost-tender plants need protection or harvest. These dates represent 30-year central tendencies; actual year-to-year variation can shift either bookend by 7-14 days, and local microclimate features within Cheyney University — cold-air drainage on calm clear nights, slope aspect, distance from any nearby lake or river — can push the practical frost window earlier or later than the regional average.
