Record-breaking heat engulfs the Northland on this October 4th, 2025.
Northeast Minnesota and northwest Wisconsin experienced widespread 80s today, about 25 degrees above the early October average. However, while the southerly winds were strong, they couldn’t fully counter the northeast wind near Lake Superior. Those light onshore breezes from the lake kept temperatures in the 60s and 70s, which is still warmer than usual for this time of year.
New record high temperatures were set today (October 4) in the Northland.
