Great Lakes Water Level Data

Marine Weather for Canada

Great Lakes nearshore forecasts are subdivided by zone, each identified by text description and a Universal Generic Code (UGC). The different colors used in the map above have no meaning and are only intended to assist in differentiating the zones.

Great Lakes nearshore marine forecasts are issued throughout the boating season, typically beginning around April 1 and ending around December 31, dependent on ice conditions on the entrances to each individual lake. During periods of climatological extremes leading to erratic ice coverage patterns (shifting of ice edge, late/early freeze, etc.), and based on customer needs, nearshore forecasts may be issued throughout the winter to support the National Weather Service mission of protecting life and property on the waters of the Great Lakes.

These forecasts are also available via e-mail
