Regional context

Per NOAA NCEI 1991-2020 normals, Milwaukee runs from a 23°F January mean to 73°F in July, a 50°F seasonal spread, with near 33.1 inches of precipitation across about 189 wet days.

No season owns Milwaukee's rain: May reaches 3.7 inches across 18.0 days and January keeps 1.8 inches on 17.8, an even spread through Milwaukee's year. That lines Milwaukee up with places like Wauwatosa, WI, West Milwaukee, WI and Shorewood, WI, fed by overlapping storm tracks.

Milwaukee reaches its last hard frost near late-May; that is the cue for kale, peas, spinach, and parsnips. Tomatoes and peppers do best set out two weeks later in Milwaukee, once nights clear the mid-40s°F. By early-October, frost is back in Milwaukee — protect or harvest anything tender. A creek-bottom lot in Milwaukee can lag Milwaukee's last frost 7-10 days behind a south slope.

Similar climates: Wauwatosa, WI, West Milwaukee, WI, Shorewood, WI, Whitefish Bay, WI, Glendale, WI.

Naturalist notes

Late May brings the first blooms of wild lupine across Wisconsin's sandy soils, their purple spikes emerging as soil temperatures consistently reach 60°F.

American robins begin their dawn chorus in earnest during the third week of April, when daylight extends past 13 hours.
