Regional context
Summit View's climate, per the NOAA NCEI 1991-2020 normals from the nearest reporting station, runs cold-winter and warm-summer. January means hover near 40°F while July climbs to 64°F — a 24°F seasonal swing typical of northern-tier latitudes. Annual precipitation totals about 45.1 inches spread across roughly 110 days with measurable rain or snow.
Precipitation peaks in the cool season: November averages 7.1 inches across 14.1 days with measurable rain, mostly from frontal systems and winter storms, while August bottoms out at 0.9 inches across just 2.2 rainy days during the drier warm-season stretch. The pattern groups Summit View with places like Clover Creek, WA, Summit, WA and Frederickson, WA, places whose summer-dry rhythm and cool-season-wet recharge run on the same regional storm-track exposure.
The frost-sensitive growing window opens around late-May, when overnight lows reliably clear freezing for cool-season crops like peas, lettuce, spinach, and radishes. 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. The dates above are 1991-2020 normals; in a given year either bookend can move 1-2 weeks either direction. Within Summit View, 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.
