Open Lake Forecast for Lake Superior
National Weather Service Marquette MI
357 PM EST Sun Nov 28 2021

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
A 30.0 inch ridge axis has begun to extend into the
Upper Great Lakes region this afternoon. This ridge is expected to
remain until Monday, as the next trough of 29.7 inches crosses
the Upper Great Lakes late Monday into early Tuesday. The next
ridge of around 30.0 inches moves in by mid-week, and is expected
to move out by late Wednesday as a 29.4 inch trough approaches
and crosses Lake Superior. This trough is expected to continue
deepening to 29.3 inches by early Thursday as it nears the
Ontario/Quebec border. The next 30.0 inch ridge then moves in
around Thursday night, although yet another trough, this one about
29.8 inches, grazes past Lake Superior late Friday into early
Saturday.
