Regional context
Kenmar'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 74°F — a 46°F seasonal arc typical of the mid-latitude bands. Annual precipitation runs about 42.7 inches spread across roughly 83 days with measurable rain or snow each year.
Rainfall stays relatively even across the calendar: September tops out at 4.5 inches across 6.8 days with measurable rain, and February settles around 2.4 inches across 5.9 rainy days — a comparatively narrow seasonal range. The balanced distribution lines Kenmar up with places like Faxon, PA, Montoursville, PA and South Williamsport, PA, all of which run on overlapping storm tracks rather than a single seasonal moisture source.
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-soil crops — tomatoes, peppers, eggplant — wait until soil temperatures reach the mid-50s°F, usually two weeks past the last-frost date. 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 Kenmar, 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.
