GRAND HAVEN, Mich. (WOOD) — Northeast winds will keep nearshore waves under 2 feet through most of this week.

The good news is that green flag swimming conditions will be the rule pretty much all of this week. The bad news you are not going to want to swim in most locations as we had a classic upwelling event take place and that has allowed lake water temperatures to crash along the lakeshore. Grand Haven’s water temperature Tuesday was 80 degrees. Friday it was 45! It was back to 56 on Sunday, but Lake Michigan nearshore will stay chilly right through the middle of this week.

This time of the year is typically when the Great Lakes as a whole peaks with their warmest water temperatures. I recall a few years back vacationing in Munising in the U.P. and jumping off small cliffs at Grand Island. The water was cold but not enough you couldn’t adjust to. The water temperature as of last Thursday is 66 degrees. Not bad for Lake Superior!

LOOKING TO NEXT WEEK

There isn’t any significant heat (90s) or really high humidity in sight.

The latest 8-14 day temperature outlook has remaining near average through the 25th of August.
