Historical weather data, all-time temperature records, and monthly climate averages for Kenosha, WI. Explore typical weather conditions by week for trip planning, and see how today compares to the historical record.
April 4th in Kenosha is classic early spring ambiguity — the average high of 49° and low of 32° put you right on the frost line. The date has swung from a balmy 75° back in 1997 to a brutal 12° in 1982, so don't put the winter coat away just yet. There's a 41% chance of rain, but snow is mostly a non-factor at just 3%.
Kenosha's weather has real range — 82 years of records show a 136-degree spread between its all-time high of 105° on July 4, 2012 and its bone-chilling low of -31° on January 16, 1982. On the wet side, a single October day in 1965 dropped 5.66 inches of rain, and a February 2011 snowstorm buried the city under 16.8 inches in one shot.
Summer is the sweet spot: the warmest week of the year runs July 16–22 with average highs of 81°, though it's also the wettest stretch with about an inch of rain per week. Winter bites hard — January highs hover around 29–30° during the coldest stretch of mid-January. Spring and fall are short transitions, with April highs averaging 53° and November already back down to 47°.
