Guide to marine weather forecasts

Environment Canada (EC) provides a marine forecasting service to mariners and marine interests. This enables them to make informed decisions about marine weather conditions that may impact their safety, security or operations. EC also provides marine forecasts in order to meet Canada’s treaty obligations under the International Maritime Organization’s Safety Of Life At Sea (SOLAS) Convention. 

There are three main marine forecast bulletins issued by EC. In addition to this, descriptive marine synopses are issued by the Department in conjunction with these marine forecast bulletins. The three marine forecast bulletins are each described in further detail in the next section.
