(WFRV)- While most of our record highs stood to see another day on Sunday, Green Bay warmed up to 94° on the afternoon of Sunday, June 22, 2025, tying the record set back in 1910. However, this was quite a vulnerable record, as Appleton’s record high was 99° set back in 1911 and Oshkosh’s was 98° set back in 1988.
Either way, it was quite a warm day in northeast Wisconsin, the second of three days with highs in the 90s. Heat index values reached the triple digits as well.
