Regional context
Cuyuna'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 70°F — a 59°F seasonal swing typical of northern-tier latitudes. Annual precipitation totals about 24.5 inches spread across roughly 47 days with measurable rain or snow.
Precipitation runs summer-dominant here: July averages 4.3 inches across 6.1 days with measurable rain, driven mostly by warm-season storms and thunderstorm activity, while February drops to just 0.4 inches across 1.3 rainy days under drier cool-season air. The warm-season-wet rhythm lines Cuyuna up with places like Crosby, MN, Deerwood, MN and Ironton, 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. Those dates are 30-year averages; the actual frost-free window in a given year can vary by 10-14 days at either end. Neighborhood-scale variation in elevation and cold-air pooling means the practical last-frost date inside Cuyuna can lag the regional mean by 5-10 days in low spots, and a bench position with good cold-air drainage can run a week ahead.
