open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
150 pm cdt fri sep 11 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...

30.0 inch high pressure is shifting into southern ontario this 
afternoon, allowing winds to shift generally southerly across the 
open waters of lake michigan. southerly winds will continue to 
increase into tonight as 29.4 inch low pressure moves from the 
northern great plains toward the us-canadian border. winds will 
shift out of the west-northwest during the day saturday as a cold 
front moves across the lake. expecting wind gusts to remain 
primarily in the 25-30 knot range from this evening through 
saturday, though occasional gusts approaching gale thresholds 
can't be completely ruled out. currently anticipating any such 
gusts to remain brief and isolated enough to preclude the need for
gale warnings, but will continue to monitor trends. isolated 
showers and thunderstorms are possible ahead of the approaching 
cold front, with severe weather hazards not expected.

30.2 inch high pressure will build in from the northern great 
plains sunday night into monday, bringing decreasing winds 
saturday night through sunday & light/variable winds sunday night 
into monday. the high will move east of the waters monday 
afternoon & evening, resulting in a south-southeast wind shift. 
winds will increase further & veer south-southwesterly monday 
night into tuesday as 29.4 inch low pressure develops over 
manitoba. gales continue to appear likely during this time frame, 
with headlines becoming necessary in later forecasts if trends 
continue to hold. periods of showers and thunderstorms will 
accompany the developing low from as early as monday evening 
through at least tuesday afternoon. widespread severe weather 
hazards appear low over lake michigan at this time, though an 
isolated stronger storm with gusty winds can't be entirely ruled 
out. winds will trend northerly behind a cold front tuesday night 
into wednesday, steadily tapering away from gale thresholds in the
process.
