open lake forecast for lake ontario
national weather service buffalo ny
1002 am est wed nov 5 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...low pressure over the upper great lakes will deepen from 
29.6 inches to 29.4 inches as it passes along or just north of the 
north shore of the lake this afternoon into this evening, before 
making its way across new england tonight while further 
strengthening to 29.2 inches. in its wake, a 30.2 inch high will 
build from the ohio valley to the mid-atlantic states thursday, then 
will slide out to sea through friday while allowing a 29.4 inch low 
to track from the upper great lakes to quebec and push its trailing 
cold front across the lake friday night. another 29.5 inch surface 
low will then track from the ohio valley to new england sunday and 
monday.

for waters beyond five nautical miles of shore on lake michigan.

waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will
occasionally be encountered.

.synopsis...

winds will turn to northwesterly behind a low pressure system
around 29.7 inches and associated cold front this morning. winds 
will approach gale force later this morning through this 
afternoon until the pressure gradient weakens and the low moves 
into the new england states. 

this evening winds will diminish and become light as high 
pressure moves from the northern plains into the ohio river 
valley. light northwest winds will turn to southerly thursday. 
winds will increase again as the pressure gradient tightens ahead 
of an incoming low pressure around 29.4 inches thursday night. 
there is a potential for some southerly gales during this time. 
this low will cross northern minnesota and move over lake superior
dragging a cold front across lake michigan. behind the front 
friday morning, brisk northwest winds are expected. these brisk 
north to northwest winds will persist through monday.

into the new england states. 

this evening winds will diminish and become light as high 
pressure moves from the northern plains into the ohio river 
valley. light northwest winds will turn to southerly thursday. 
winds will increase again as the pressure gradient tightens ahead 
of an incoming low pressure around 29.4 inches thursday night. 
there is a potential for some southerly gales during this time. 
this low will cross northern minnesota and move over lake superior
dragging a cold front across lake michigan. behind the front
