open lake forecast for lake ontario
national weather service buffalo ny
1002 am edt fri jul 10 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 30.0 inch high will build into the upper great lakes 
today, then strengthen to 30.2 inches while building across the 
lower great lakes tonight through the weekend, before expanding east 
into new england monday. the 30.2 inch high will then drift south 
into the mid atlantic tuesday, allowing a warm front to pass across 
the lake.
