258 am cst thu nov 6 2025

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...

light northwest winds will turn south today, as high pressure 
around 30.3 inches pushes out and low pressure around 29.5 inches
pushes in. southerly winds increasing this evening into tonight 
ahead of the approaching low pressure. there is increasing 
confidence in a round of gales during this period, with a gale 
warning now in effect for the entire lake tonight.

northwest during the day friday behind the low and an associated 
cold front. more periods of gusty winds will be possible the 
second half of the weekend into at least early next week.
additional gales becoming more likely especially for sunday into
