Mind-Blowing Michigan Weather: 90 Degrees to 49 Degrees in Just 50 Miles

You have no doubt heard the most lame weather clichés about Michigan. Don't like the weather? Wait five minutes. Need the heat in the morning and air conditioning in the afternoon?

However, there are real weather days and situations that give truth to the clichés. One of those occurred in mid-May 2025. A drastic temperature gradient set up across Michigan's Upper Peninsula on May 12.

Here's the incredible swing from hot to cold. The village of L'Anse clocked a temperature of 90 degrees - one of the warmest temperatures in Michigan and record warmth for this region of Michigan this time of year.

Just 50 miles north in the Keweenaw Peninsula, the hamlet of Bete Grise saw a temperature of just 49 degrees, that's a 41 degree temperature swing in just under 50 miles. 48 by our count on Google Maps.

The huge temperature swing was noticed by the Michigan Storm Chasers Facebook page. They also had the explanation for the stark difference.
