April 4 in Madison lands right in that unpredictable stretch of early spring — average highs of 57° with lows still dipping to 35°. The date has seen everything from a balmy 79° back in 1981 to a brutal 12° in 1954, so pack layers. There's about a 1-in-3 chance of rain, but snow is essentially off the table at this point.
Madison's weather has some serious range — 94 years of data shows a spread of 133 degrees between its coldest (-26° in February 1934) and hottest (107° in July 2010) days on record. A single August storm in 1971 dumped 8.76 inches of rain, and a January 1961 snowstorm buried the area under 20 inches in one shot.
Summer is the clear sweet spot, with mid-July highs averaging 87° and late July being the wettest stretch at about 1.36 inches per week. If you're cold-averse, avoid mid-January, when average highs barely crack 38°. Spring and fall offer a comfortable middle ground, with April and October averaging 62° and 66° respectively.
