April 4th in Chippewa Falls is classic shoulder-season chaos — the date's warmest high hit 79° back in 2021, but 1995 brought a brutal 6° low, a 73-degree swing on the same calendar day. Expect average temperatures in the upper 40s for highs and upper 20s for lows, with about a 1-in-3 chance of any precipitation and a 14% shot at snow.
Chippewa Falls plays for keeps on both ends of the thermometer — the all-time high of 104° in July 1988 and a jaw-dropping -45° in January 1951 represent a 149-degree swing in recorded history. A single September day in 2000 dropped nearly 6 inches of rain, while December 2010 buried the city under 22 inches of snow in one storm.
Summer is the sweet spot here, with highs peaking around 83-84° in mid-July and the wettest stretch arriving in early August at about 1.2 inches per week. Winters are genuinely harsh — January averages just 22° for a high, so plan cold-weather visits accordingly. Spring and fall move fast, with April jumping nearly 16 degrees above March's average high as the season turns.
