- had high hopes for this morning but was a bit of a let down. thick fog at dawn and could hardly see if anything was breaking out there. once i saw there were some rideable waves i headed out in a shorty and came back in within 30sec cause the water temp dropped so much. buoy 4 miles out was still reading in the 70s so must have just been along shore that it kicked up cold. my feet/legs were aching and knew i couldnt take it. took a reading and the water temp was 52.9F. threw on a 3/2 and then a storm came through.
after lightning passed i made another go at it once the fog let up a little. fog/rain came and went through the session. rocks were extremely slippery. didnt really get any good rides, most of the bigger stuff earlier was not visible due to fog. just posting the vid for log. really glad i went out the day before - which was windy misty rain the whole session but much more fun waves and wayyy warmer water.
Upwelling can be caused by strong, persistent offshore winds-in the case of Sheboygan, that would be be west or southwest winds-that blow the warm surface water out into Lake Michigan. The colder subsurface water then rises to the top, replacing the warm water. That's how we get water temps in the 50s in late Summer when air temps may be in the 90s
@@peterlamar8546, that’s rather interesting! I never understood how water could be 50 degrees when it was 90 degrees outside. I never thought to ask. Thank you for sharing!

Great job, Aaron! I don’t think I’ve ever seen you surfing in the fog before! In the rain, yes. In the snow, yes. But never in the fog. Can you please explain what upwelling is? I can kind of picture what you might be talking about, but please inform me and anyone else who might be reading and wondering what upwelling is. Thanks!
I’ll take the liberty of fielding that question.
Our local water temps have been low 70’s for the past few weeks. Down deep, say 50 feet or more, readings in the 40’s are found. Last Thursday night there was an upwelling of that cold water resulting in a 20 degree drop in surface temp. That’s a recipe for fog.
Fortunately, a 2 day north swell has since brought the warm surface water back to our shores.
@@charleskoehler9873, thank you for your thoughtful and helpful explanation! 👋🏻
Charlie, I truly appreciate you sharing your knowledge and wisdom about upwelling and fog. I’m sure your name will come up when I’m watching Aaron surfing in the fog in the future! LOL 🏄♂️
