national weather service buffalo ny
1011 pm edt sun sep 13 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

across the lake on wednesday and be followed by a ridge averaging 
30.1 inches and building briefly from the upper great lakes. on 
thursday, the front may shift northward to the lake, but then shift 
back south later in the day as a weak low of 30.0 inches wobbles 
eastward across the central great lakes. behind the low and front, a 
ridge averaging 30.2 inches should build from the upper midwest 
through friday.
