This buoy out in the middle of the lake is reporting 62.6F. Brrrr. You are using very shallow water temps heated up by the sun. If the winds blows that 62F water to shore, you ain't going swiming. I'm sure that happens.
And the historical data for that buoy shows the avg lake temps peaks at 22C in August.
But who swims in the middle of the lake? If you swim at the beach where the water is measured at say 76F, then that is the temp not the 66F in the middle of the lake.

It is a snapshot of the temps without winds blowing that cold water over towards the coast. If east winds came up it would pull that colder water towards shore. I would like to see long term avg temps of the water along the shore at Lake Michigan. I can't imagine it averaging 80f for more than a few days during very hot summers.

That can and does happen. Quite annoying when it does, but it's not that often.... You said it yourself, that you get upwelling which drops your coastal temps.... This is why I love the Gulf Coast. Don't have to worry about any of that

Like I said, in most summers the shoreline temps along Chicago peak around 80 degrees during the month of August (and in Indiana a little warmer than that). For how many days? That depends. It could be as little as for a few days to a few weeks, and into September. In very hot summers shoreline temps have reached above 85 degrees, and in hot summers even the mid lake buoy which is placed 50 miles out, in a part of the lake that is known as the South Chippewa Basin actually reaches over 80 degrees as well. It is located in one of the deepest parts of the lake at 530 ft deep, deepest is a few miles from where the buoy is and the depth is at 902ft. Why do you feel that buoy represents "Chicago's water temps"?

For Chicago-area swimmers, the shore temperature is taken at a depth of about 15 feet at the Jardine Water Purification Plant near Navy Pier. In most summers the water temperature usually peaks around 80 degrees in August. Open lake water temperatures, which are usually lower than the shore readings, are recorded at the NOAA buoy moored in Lake Michigan about 50 miles east-southeast of Milwaukee and have been archived since 1981. The highest water temperature recorded there was 81.3 degrees on Aug. 18, 1995, a reading that occurred during a very hot summer that led to Chicago’s deadly July 12-16 heat that killed more than 750 people.
I'll have to try 30C SSTs someday.. but I have a feeling it would be too warm. The point of going in the sea for me is either to cool down or to catch the waves, which means I am active and therefore find 25C temps warm
What i'm not allow to express my views? It seems to me that you took offense to this comment
I just think it's cold... By definition it's cold.
Going outside for any significant amount of time unprotected in a Chicago winter can kill you. Same as going in 20C water without a wet suit.
Erm you were the one that took issue with me saying it wasn't cold, I said that people have different temperature tolerances & you didn't just say in your own personal opinion it is cold, but that factually it is cold
Going in 20C water will not kill you. Fact. Thousands do it at beaches in the UK & I have never heard of anyone getting hypothermia or dying from going for a swim in the sea in the UK
I suggest you stop searching for OTT infographics & trawling the internet for information & actually listen to the opinions of people who have experience of certain climates etc..
I just think it's cold... By definition it's cold.
I agree with you. Sea water at 20°C feels definetely cold to me, it is not a pleasant temperature for swimming.
