Regional context

Drawing on NOAA NCEI 1991-2020 normals, Lavina's January averages 23°F and July 69°F — 46°F apart — while precipitation totals roughly 15.1 inches over some 41 days.

Summer convection drives Lavina's precipitation: June logs 3.0 inches on 5.7 rainy days, against February's 0.4 inches on 2.1 — warm-season storms carry Lavina's moisture. That summer-storm rhythm groups Lavina with places like Broadview, MT, Ryegate, MT and Golden Valley Colony, MT.

Lavina's growing window opens around late-May, once Lavina's overnight lows stop freezing — sow kale, peas, spinach, and parsnips. Warm-soil crops in Lavina wait about two weeks past Lavina's last frost, once the soil warms. It shuts near early-October, when freezes return to Lavina and tender plants need cover. Within Lavina, cold-air pooling chills low spots by 5-10°F, shifting Lavina's local frost dates.

Similar climates: Broadview, MT, Ryegate, MT, Golden Valley Colony, MT, Mountain View Colony, MT, Klein, MT.
