open lake forecast for lake ontario
national weather service buffalo ny
403 am edt fri apr 24 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 strong 30.7 inch high centered well to the north will 
remain ridged south across the lake through today. a 29.6 inch low 
over the upper great lakes this morning will nudge a warm front 
toward the lake as it moves into the central great lakes this 
afternoon. this low will slightly weaken to 29.7 inches as it passes 
just southwest of lake tonight while nudging the warm front a bit 
further east over the lake. the low then slide southeast into the 
mid atlantic region saturday forcing the front back to the southwest 
of the lake. a 30.2 inch area of high pressure will then build 
across the lower great lakes saturday night through monday. a 29.4 
inch area of low pressure over the great plains monday night, will 
advance northeast into the upper great lakes later monday night into 
tuesday morning while pushing an attendant warm front across the 
lake. the 29.4 inch low will then continue northeast to james bay 
tuesday night sending an attendant cold front across the lake.
