Water temp???

Besides air temperature, humidity has a big effect. High dew point air (humid) retards evaporation, which has a cooling effect. When a dry air mass comes in with some NW wind behind it, the surface temperature drops notably.

Water temp is 10 degrees warmer than this time last year. Reading 78 on my chart plotter (1’ deep but air is cooler) all across area north of Cow today. Still above my swimming threshold.....isn’t this September?

The water temperature yesterday at East Bear Island was 79 degrees. 🐻

Pretty sure the warmest lake temp is usually the end of Aug/beginning of Sept.

Incorrect-a-mondo! ...... warmest Lake Winni water temp going back to 1822 ...... has almost always been about August 4.

They didnt have thermometers in 1822 but I'm probably wrong and mid August would be more like it.

Trying to find historical average lake temps.Help

I've got a model of Galileo's "thermometer"—invented in 1593. Not a mercury thermometer, I feared it might freeze and break in our unheated cottage last winter. It came through OK. It uses mineral spirits as a suspension medium. Some "Galileo thermometers" sold today don't recommend freezing temperatures.

I think the weather has changed. It seems the last couple of weeks of August used to be windy and a bit cooler but it doesn’t seem that way any more.
