Regional context
Nezperce's climate, per the NOAA NCEI 1991-2020 normals from the nearest reporting station, runs cold-winter and warm-summer. January means hover near 29°F while July climbs to 64°F — a 35°F seasonal swing typical of northern-tier latitudes. Annual precipitation totals about 20 inches spread across roughly 62 days with measurable rain or snow.
Rainfall stays relatively even across the calendar: May tops out at 2.7 inches across 7.1 days with measurable rain, and August settles around 0.8 inches across 2.3 rainy days — a comparatively narrow seasonal range. The temperate, evenly-distributed pattern groups Nezperce with places like Ferdinand, ID, Kamiah, ID and Craigmont, ID, where seasonal storm tracks deliver moisture more uniformly than the continental interior.
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-season transplants — tomatoes, peppers, and basil — typically wait two weeks past that date to avoid late spring cold snaps. The window closes around early-October, when overnight lows resume dipping below freezing and frost-tender plants need protection or harvest. These are 30-year central tendencies; year-to-year frost dates can move by up to two weeks. Local features matter: a south-facing slope inside Nezperce typically runs 3-5 days ahead of the regional last-frost date, while a low-lying lot along a creek or drainage can lag the same date by a week or more on calm clear nights.
