April 5th in Stoughton is classic Wisconsin spring ambiguity — the average high of 51° sounds reasonable until you remember this date once hit 72° in 2016 and bottomed out at 11° back in 1995. With a 31% chance of precipitation and only a 1% shot at snow, the white stuff is nearly behind you, but "nearly" is doing a lot of work this time of year.
Stoughton's weather has serious range — we're talking 103° in July 2012 and -35° in January 1951, a jaw-dropping 138-degree swing between the extremes. August 2007 brought a single-day deluge of 6.03 inches, and February 2008 dropped 14 inches of snow in one shot, the kind of storm that resets the local benchmark.
Summer is the sweet spot here, with highs peaking around 83–84° in mid-July before a steady retreat through fall. If you're cold-averse, January is brutal — average highs barely clear 27° during the coldest stretch of the year. Late June through early July is both the warmest and wettest stretch, averaging over an inch of precipitation in a single week.
