April 5th in Bloomington runs the full gamut — this date has seen a balmy 85° (just four years ago in 2021) and a bone-chilling 12° back in 1979. On average, expect a cool spring day with a high near 51° and a low that still dips to freezing. There's about a 1-in-3 chance of precipitation, with a small but real 8% chance it falls as snow.
Bloomington's weather history is not for the faint of heart — the thermometer has swung from a brutal -34° in January 1970 all the way up to 105° in July 1988, a jaw-dropping 139-degree range. The city also saw nearly a foot of rain fall in a single day in 1987 (9.15") and a staggering 37 inches of snow on February 6, 2026.
Summer is the sweet spot, with highs peaking around 84° during the second week of July — but winters are genuinely harsh, with average highs barely scraping 22° in early January. If you're rain-averse, late June is the wettest stretch of the year. Spring and fall offer mild transitions, but both seasons can still throw a freeze at you well into April and again by November.
