open lake forecast for lake ontario
national weather service buffalo ny
402 pm edt wed oct 7 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 sweep eastward across the lake this 
evening through early thursday morning. behind the front, a weak 
trough averaging 29.7 inches should linger over the lake through 
thursday. during thursday night 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 should 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.
