Regional context
Madelia's climate, per the NOAA NCEI 1991-2020 normals from the nearest reporting station, runs cold-winter and warm-summer. January means hover near 14°F while July climbs to 72°F — a 58°F seasonal swing typical of northern-tier latitudes. Annual precipitation totals about 33.1 inches spread across roughly 59 days with measurable rain or snow.
Precipitation runs summer-dominant here: June averages 4.9 inches across 8.5 days with measurable rain, driven mostly by warm-season storms and thunderstorm activity, while February drops to just 0.8 inches across 1.7 rainy days under drier cool-season air. That wet-warm-summer pattern groups Madelia with places like La Salle, MN, Hanska, MN and Lewisville, MN — a regional cohort where summer thunderstorm season carries more than half the 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-season transplants — tomatoes, peppers, and basil — typically wait two weeks past that date to avoid late spring cold snaps. 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 Madelia 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.
