Regional context
Spicer's climate, per the NOAA NCEI 1991-2020 normals from the nearest reporting station, runs cold-winter and warm-summer. January means hover near 11°F while July climbs to 72°F — a 61°F seasonal swing typical of northern-tier latitudes. Annual precipitation totals about 31.4 inches spread across roughly 61 days with measurable rain or snow.
Precipitation runs summer-dominant here: June averages 4.9 inches across 8.2 days with measurable rain, driven mostly by warm-season storms and thunderstorm activity, while January drops to just 0.9 inches across 3.1 rainy days under drier cool-season air. That summer-storm-driven distribution puts Spicer in a cohort with places like New London, MN, Kandiyohi, MN and Willmar, MN, all of which depend on warm-season convective activity for the bulk of their annual moisture.
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. The dates above are 1991-2020 normals; in a given year either bookend can move 1-2 weeks either direction. Within Spicer, 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.
