open lake forecast for lake ontario
national weather service buffalo ny
1002 pm edt sat jul 11 2026

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 large 30.2 inch high will build south across the lower 
great lakes through this weekend, before sliding east into new 
england monday, then off the coast by tuesday. this will allow a 
warm front to sweep northeastward across the lake tuesday, followed 
by a cold front pushing south across the lake on wednesday. the 
frontal boundary will then remain south of the lake thursday.
