Marine Atlantic weather describes the wind, fog, and sea conditions that affect ferry crossings between Newfoundland and Nova Scotia. The live forecast above gives current conditions; seasonal fog and strong winds are the main reasons for schedule changes, so check it before you travel.
What causes Marine Atlantic crossings to be delayed or cancelled?
Fog is the most common disruptor, especially from late spring into summer, reducing visibility below safe limits. Strong winds—generally sustained above 40–50 km/h—and high waves also force cancellations. If you need the marine atlantic schedule today, the live forecast above shows the wind and visibility that matter most.
For marine atlantic cancellations today, look for a marine atlantic weather advisory issued by Environment Canada. These advisories highlight when fog, gale-force winds, or freezing spray are expected along the Cabot Strait route.
