open lake forecast for lake superior

400 pm est sat jan 24 2026

for waters beyond 5 nautical miles of shore on lake superior.

waves are the significant wave height - the average of the
highest 1/3 of the wave spectrum. occasional wave height is the
average of the highest 1/10 of the wave spectrum.

.synopsis...

30.7 inch high pressure centered over the lower great lakes 
maintains 30.6 inch ridging over lake superior this evening. ridging 
over the lake weakens to 30.3 inches into sunday, then further to 
around 30.1 inches into monday, as a 29.6 inch low moves northeast 
along the atlantic coast. a 29.8 inch clipper low crosses the lake 
monday night into tuesday. another clipper low, much weaker at 30.1 
inches, grazes the northeast portion of the lake on wednesday. a 
strong high pressure descending from the canadian prairie around 
30.7 inches late next week brings ridging back to lake superior, 
likely persisting into next weekend.
