open lake forecast for lake ontario
national weather service buffalo ny
402 am edt wed jun 18 2025

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 29.4 inch low pressure passing well north of the lake today will 
leave a cold front west of the lake. along this stalled front a 
deepening area of low pressure to 29.5 inches will advance from the 
ohio valley this morning to west of the lake late tonight, and then 
north of the lake thursday, while dragging a cold front across the 
lake midday thursday. a 30.1 inch high builds northeast across the 
lake friday, and exits east of the lake on saturday. while a complex 
of thunderstorms may dive southeastward near or across the lake 
saturday night, this now 30.2 inch surface high pressure will remain 
anchored over the eastcoast sunday.
