open lake forecast for lake ontario
national weather service buffalo ny
402 am edt thu oct 8 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 cold front will finish crossing eastward across the 
lake this morning. behind the front, a weak trough averaging 29.7 
inches should linger over the lake through today. tonight through 
friday, a ridge averaging 30.1 inches should affect the lake as the 
parent high pressure center moves from the western great lakes 
toward the central appalachians. a warm front will sweep northward 
across the lake friday night as the ridge begins to exit eastward. 
on saturday through monday, a weak trough averaging 29.9 inches 
should overspread the eastern great lakes generally from the south 
as isaias and its eventual remnant low approaches from the north-
central gulf coast and eventually the mid ohio valley and vicinity.
