This was sunset at the South Haven buoy Monday evening. The surface water temp. at the buoy reached 82° Monday late afternoon. That’s about as warm as I have ever seen it. It’s a combination of warm air, lots of sunshine and very light winds (the wind at the buoy at 10 pm Monday was 0.0 mph – dead calm – and the waves were running 3″. The water temp. at a depth of 23 feet was 60.0° and at 49 feet it was 45.4°. The next time we get a strong wind, it’ll stir the water and the surface temperature will drop.

High Temps. in West Michigan 7/6/20

Here’s high temperatures from Monday. Lots of low-mid 90s with a few upper 80s at the lakeshore airports. The high temp. at the Muskegon Beach was 80°. At the Chicago water intake, the temp. only varied from 79° to 82° during the day.

Consecutive 90-degree days

Muskegon has now had 8 days in a row with temperatures of 90 degrees or warmer. That ties the reccord set in 1947. Grand Rapids has had 5 days in a row of 90-degree heat. That’s a top ten string since 1900. We had two separate stretches of consecutive 90-degree days in July 2012. Kalamazoo is up to 8 days in a row of 90-degrees…also a top 10 longest streak in the last 20 years. Here’s Grand Rapids radar:

We do have a chance of a shower or t-shower today…There will be a few showers and storms this morning, mainly north of G.R. Like I’ve been saying…if you get rain, count yourself lucky – this is an overall dry pattern. Here’s regional radar:
