open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
843 am cst fri jan 9 2026

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...

strong low pressure around 29.3 inches will continue to lift  
northeastward across eastern ontario into quebec. gusty southwest
winds with gales linger across the far southern third of the lake
this morning, but west to northwest gales are expected to develop
across the entire lake later later this morning into the midday 
and afternoon hours. gale warnings are in effect. 

winds will gradually weaken this afternoon as high pressure 
around 30.2 inches works its way across lake michigan through 
tonight. meanwhile, an area of low pressure lifting through the 
southern plains and an additional area of low pressure digging 
into the upper midwest will interact, merging over the great 
lakes region into saturday. expect west-northwesterly winds over 
lake michigan to increase on the backside of this deepening area 
of low pressure as it lift into eastern ontario/quebec. gales may
develop in association with this feature. another area of high 
pressure will build across the region for sunday before another 
low traverses the region early next week.

open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
843 am cst fri jan 9 2026

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...

strong low pressure around 29.3 inches will continue to lift  
northeastward across eastern ontario into quebec. gusty southwest
winds with gales linger across the far southern third of the lake
this morning, but west to northwest gales are expected to develop
across the entire lake later later this morning into the midday 
and afternoon hours. gale warnings are in effect. 

winds will gradually weaken this afternoon as high pressure 
around 30.2 inches works its way across lake michigan through 
tonight. meanwhile, an area of low pressure lifting through the 
southern plains and an additional area of low pressure digging 
into the upper midwest will interact, merging over the great 
lakes region into saturday. expect west-northwesterly winds over 
lake michigan to increase on the backside of this deepening area 
of low pressure as it lift into eastern ontario/quebec. gales may
develop in association with this feature. another area of high 
pressure will build across the region for sunday before another 
low traverses the region early next week.
