Driven by complex Interactions between the Atmosphere, Water and the Surrounding Land, the Weather Conditions on Canada’s Oceans, Lakes and Rivers can be harsh and unstable.

Professional and Recreational Mariners alike rely on accurate Marine Weather Forecasts to provide them with the notice they need to seek Safe Shelter or take other actions to protect their Passengers, Vessels and Cargo from harm.

Environment Canada addresses this need by Forecasting Marine Weather 24 hours a Day, all Year round.

The Marine Forecasts cover:

Pacific and Atlantic coasts
Arctic waters
The Great Lakes
The St. Lawrence River, and many other major bodies of water
