Regional context
Wye's climate, per the NOAA NCEI 1991-2020 normals from the nearest reporting station, runs cold-winter and warm-summer. January means hover near 26°F while July climbs to 70°F — a 44°F seasonal swing typical of northern-tier latitudes. Annual precipitation totals about 14.4 inches spread across roughly 44 days with measurable rain or snow.
Rainfall stays relatively even across the calendar: June tops out at 2.2 inches across 5.9 days with measurable rain, and July settles around 0.8 inches across 1.9 rainy days — a comparatively narrow seasonal range. The balanced distribution lines Wye up with places like Orchard Homes, MT, Frenchtown, MT and Missoula, MT, all of which run on overlapping storm tracks rather than a single seasonal moisture source.
The frost-sensitive growing window opens around late-May, 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 early-October, when overnight lows resume dipping below freezing and frost-tender plants need protection or harvest. Those dates are 30-year averages; the actual frost-free window in a given year can vary by 10-14 days at either end. Neighborhood-scale variation in elevation and cold-air pooling means the practical last-frost date inside Wye can lag the regional mean by 5-10 days in low spots, and a bench position with good cold-air drainage can run a week ahead.
