open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
212 pm cdt sat mar 28 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...

widespread gales are not anticipated across the open waters through 
the duration of the forecast period. currently centered over 
indiana, 30.5 inch high pressure will advance into the mid- 
atlantic this afternoon through tonight as 29.7 inch low pressure
builds into the northern great plains, resulting in increasing 
south to southwesterly winds across lake michigan. widespread 
20-25 knot gusts are expected over the northern half of the 
waters, with a few gusts to 30 knots possible over the far 
northern lake. breezy southwest winds will continue through 
tomorrow as a cold front begins to approach the waters from the 
north. the front will gradually advance south across lake michigan
sunday night through tuesday. this will result in generally east-
northeast winds across the northern half of the lake with 
southerly winds further south. a few gales are possible over 
southeastern lake michigan monday night, but aren't expected to be
widespread. periods of showers and thunderstorms will accompany 
the slow-moving front, with a few stronger storms possible monday 
night and once again on tuesday. large hail would be the primary 
threat in any stronger storms.

winds will trend northerly behind the departing cold front tuesday 
evening through wednesday. will be monitoring trends for a few gusts 
approaching gale force tuesday evening/night, with the current 
expectation being for any such gusts to be isolated. 30.7 inch 
high pressure will shift from ontario to quebec through the late 
week time period as 29.8 inch low pressure builds into the ohio 
river valley, allowing winds to trend east-northeasterly. 
additional rain and snow will accompany the approaching/passing 
area of low pressure thursday into next weekend.

open lake forecast for lake superior
national weather service marquette mi
400 pm edt sat mar 28 2026

for waters beyond 5 nautical miles of shore on lake superior.

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...

this afternoon, a 30.5 inch low resides over lake erie and will 
track over the east coast tonight. upstream on sunday, a 29.7 inch 
low organizes over the central plains, lifting a 30.0 inch trough 
over lake superior by sunday night. this trough lingers over the 
great lakes and slowly deepens with time early this week, before the 
low pushes through at 29.5 inches on tuesday. as the low tracks 
along the st. lawrence seaway late tuesday, 30.3 inch high pressure 
builds over the northern plains, gradually building pressure over 
the upper great lakes by wednesday as the high presses east through 
ontario at around 30.5 inches. thursday, the high builds to 30.8 
inches over quebec while 29.3 inch low pressure organizes in the lee 
of the rockies.
