Regional context
Kimberly's climate, per the NOAA NCEI 1991-2020 normals from the nearest reporting station, runs cold-winter and warm-summer. January means hover near 18°F while July climbs to 71°F — a 54°F seasonal swing typical of northern-tier latitudes. Annual precipitation totals about 33.2 inches spread across roughly 70 days with measurable rain or snow.
Precipitation runs summer-dominant here: June averages 4.7 inches across 8.0 days with measurable rain, driven mostly by warm-season storms and thunderstorm activity, while February drops to just 1.1 inches across 3.5 rainy days under drier cool-season air. The warm-season-wet rhythm lines Kimberly up with places like Combined Locks, WI, Little Chute, WI and Appleton, WI, 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. These dates represent 30-year central tendencies; actual year-to-year variation can shift either bookend by 7-14 days, and local microclimate features within Kimberly — cold-air drainage on calm clear nights, slope aspect, distance from any nearby lake or river — can push the practical frost window earlier or later than the regional average.
