open lake forecast for lake ontario
national weather service buffalo ny
1002 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 weak trough averaging 29.7 inches lingers over the 
lake 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. the ridge 
should exit slowly eastward friday night through saturday and allow 
a warm front to drift northward across the lake. on sunday through 
tuesday, a weak trough averaging 29.9 inches should overspread our 
area generally from the west and a cold front should sweep eastward 
across the lake on tuesday. simultaneously, the future remnant low 
of isaias should wobble northeastward from near the lower ohio 
valley to atlantic waters south of nova scotia and weaken to 29.6 
inches during sunday through tuesday.
