April 5 in Aurora sits squarely in that unpredictable shoulder season — expect a high near 55° and a low around 34°, but 130 years of data show it can swing wildly, from a scorching 83° in 1988 to a brutal 14° in 1975. There's a 37% chance of rain today, though snow is nearly off the table at just 2%.
Aurora has seen some genuinely extreme weather over its 130+ years of records — a suffocating 111° in July 1936 and a bone-cracking -26° in January 1985 paint a picture of a city that gets the full Midwest treatment. The wettest day on record, 16.91" on July 18, 1996, and a 17" snowfall in a single February 2011 day round out a city that doesn't do anything halfway.
Summer is Aurora's sweet spot, with late July averaging a high of 86° and June bringing the most rainfall at just over an inch per week — pack an umbrella if you're visiting then. Winters are genuinely cold, with early January highs averaging just 31°, so plan accordingly if you're heading out between December and February.
