Regional context
Wylandville's baseline climate, derived from NOAA NCEI 1991-2020 normals at the nearest reporting station, swings from a January mean of 28°F to a July mean of 73°F — a 44°F seasonal arc typical of the mid-latitude bands. Annual precipitation runs about 41.3 inches spread across roughly 87 days with measurable rain or snow each year.
Rainfall stays relatively even across the calendar: June tops out at 4.5 inches across 8.1 days with measurable rain, and February settles around 2.5 inches across 6.3 rainy days — a comparatively narrow seasonal range. The temperate, evenly-distributed pattern groups Wylandville with places like Eighty Four, PA, Strabane, PA and Thompsonville, 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 Wylandville — 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.
