open lake forecast for lake ontario
national weather service buffalo ny
402 am est sun dec 21 2025

for waters beyond five nautical miles of shore on lake ontario

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...a 30.1 inch high over the lower great lakes will drift 
off the atlantic coastline tonight. a 29.5 inch low moving across 
ontario and quebec will push its attendant cold front across the 
lake sunday. a large 30.6 inch high will then build east across the 
lake monday. a 29.8 inch low just north of lake superior tuesday 
will pass north of the lake, resulting in a pair of fronts passing 
across the region.
