Habitat 67 • Surf Spot Statistics

Best Surf Season (December - March)

Habitat 67 sits on the banks of the St. Lawrence River, and the numbers do not lie: there is no open-ocean swell here. The average swell height is 0.0m, the average period is 0.0s, and the wind is ideal for surfing 0% of the time in every month. That makes the 'best surf season' a relative term. From December through March, stronger westerly winds and passing winter low-pressure systems generate the most surface activity, but it remains short-period, local wind chop rather than real surf. Ice, freezing water temperatures and air that can reach -41°C make this window more of a survival test than a surf trip.

Fair Surf Season (April, October, November)

These transition months offer the best balance between manageable temperatures and a slightly more active synoptic pattern. The jet stream strengthens in October and November, and April benefits from spring storms and river runoff. Wind roses show a mix of WSW/W flow with occasional offshore NW/WNW episodes. Still, wave height remains 0.0m across all swell directions, so the only rideable days would come from an unusual local wind event aligning with an offshore breeze. Treat these months as a lottery ticket.

Low Surf Season (May - September)

Summer is the true flat spell. Weak pressure gradients, light thermal winds, and warm water sounds pleasant, but the swell data are dead: 0.0m height, 0.0s period. Westerly and southwesterly breezes dominate, and the ideal offshore quadrant is rarely strong enough to make even the river surface interesting. If you arrive between May and September, bring a surfboard only if you also enjoy paddleboarding.
