Coastal low pres will move into the Maritimes today. This will generate a W flow across the waters through mid-week. Developing low pres will emerge off the coast late in the week, potentially developing into a gale center which may pass in the vicinity of the 40N/70W benchmark sometime Fri into Sat.

What this buoy measures
This buoy is not reporting waves. Conditions above come from the sensors it does carry, and the forecast, tides and sun times on this page are regional rather than measured at the buoy.
