open lake forecast for lake ontario
national weather service buffalo ny
1002 pm edt sun sep 20 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 30.4 inch high will ridge southeastward across the lake from 
ontario province tonight. this high will then remain ridged across 
the lakes while strengthening to 30.7 inches as it slowly drifts 
east into quebec through midweek, where it will remain through 
thursday. the high will then weaken to 30.3 inches while getting 
shoved back westward into ontario province on friday in response to 
a 29.3 inch low moving northward just off the mid-atlantic and 
jersey coastline.
