Regional context
Longville's climate, per the NOAA NCEI 1991-2020 normals from the nearest reporting station, runs cold-winter and warm-summer. January means hover near 8°F while July climbs to 69°F — a 61°F seasonal swing typical of northern-tier latitudes. Annual precipitation totals about 26.6 inches spread across roughly 58 days with measurable rain or snow.
Precipitation runs summer-dominant here: July averages 4.4 inches across 7.4 days with measurable rain, driven mostly by warm-season storms and thunderstorm activity, while February drops to just 0.7 inches across 2.2 rainy days under drier cool-season air. The warm-season-wet rhythm lines Longville up with places like Whipholt, MN, Boy River, MN and Remer, MN, where the May-September stretch delivers the bulk of the year's precipitation.
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. Heat-loving transplants like tomatoes, peppers, and squash generally hold off for another 10-14 days to clear the last spring frost risk window. 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 Longville, 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.
