open lake forecast for lake ontario
national weather service buffalo ny
1002 am est sat jan 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 30.2 inch high draped across the central and eastern
great lakes will give way to another surface low that will deepen
to 29.6 inches while pushing from the upper great lakes and ohio 
valley to lower michigan today, then to southern ontario tonight and 
southern quebec sunday. in the process, this low will swing an 
initial cold front across the lake tonight, followed by a secondary 
cold front on sunday. a 30.4 inch high building over the southeast 
will then ridge north across the lake monday into tuesday, before a 
29.2 inch low pushes across ontario and quebec later tuesday into 
wednesday.
