Cold Waters and High Waves on the Great Lakes
Today station 45004 on Lake Superior is still reporting water temperature of just 38F. The normal for late July is in the mid 50s.
On Lake Michigan, 33 knot north winds produced 11.4 foot waves at the Michigan City, IN buoy yesterday morning. The large waves produced enough upwelling to drop the water temperature to 58.8 F at the southern Lake Michigan buoy. Water temperatures were around 61 before the big waves hit, which is already about 10 degrees below normal.
