Guide to Environment Canada Marine Weather Forecasts
Types of Marine Forecasts
Regular Marine Forecast
The regular marine forecast gives a description of the marine winds and weather, visibility, and/or freezing spray (if applicable), expected over the marine district. It also states any marine warnings or watches that may be in effect.
Extended Marine Forecast
The extended marine forecast is meant for longer range planning purposes and therefore only gives a description of the marine winds expected over the marine district. Marine wind warnings are not included with the extended marine forecast because of the greater potential for forecast variability in longer range outlooks.
Wave Height Forecast
The wave height forecast gives a description of the significant wave heights expected over the marine district.
The marine synopses consist of two bulletins:
- Technical Marine Synopsis - The technical marine synopsis is a brief and generic description of the main weather systems affecting the marine district.
- Marine Weather Statement - The marine weather statement is used either to describe (in further detail) marine weather conditions that may pose a hazard to marine interests; or as a way of providing additional marine weather information to supplement the marine forecast.
