Regional context

Per NOAA NCEI 1991-2020 normals, Inchelium runs from a 29°F January mean to 71°F in July, a 42°F seasonal spread, with near 19.9 inches of precipitation across about 61 wet days.

Cool-season fronts carry Inchelium's rain: December logs 2.8 inches on 7.5 days, against August's 0.7 inches on 1.7 — winter does the heavy lifting in Inchelium. That groups Inchelium with places like Twin Lakes, WA, Addy, WA and Kettle Falls, WA on the same cool-season storm track.

Inchelium reaches its last hard frost near late-May; that is the cue for kale, peas, spinach, and parsnips. Inchelium's heat-lovers — tomatoes, peppers, squash — hold off until Inchelium's frost risk clears, 10-14 days on. The season ends by early-October in Inchelium, once hard frosts set back in. Inchelium's low ground holds frost later into spring than Inchelium's benches, which run 3-5 days ahead.
