Portsalon - surf spot statistics

Best Surf Season (March - May)

Spring brings the most favorable blend of swell direction and wind at Portsalon. While the North Atlantic still pumps long-period groundswells, the frequency of swell from the optimal NNE to E sector peaks during these months, reaching nearly 6% of all observations in May. Simultaneously, offshore SSW to W winds become more consistent, with ideal wind percentages climbing to 28-32%. This window offers the highest likelihood of groomed, rippable waves, though size often maxes out in the fun to solid range (1-2m). It's a season of quality over quantity.

Fair Surf Season (October - February)

The heart of winter delivers serious size—average swell heights of 2.7-3.2m and periods of 11-12.4s—as powerful extratropical cyclones march across the North Atlantic. However, the swell's dominant W to NW orientation (not optimal for this NE-facing beach) and consistently strong onshore winds from the north and east (blowing directly from the bad quadrant) mean only about a quarter of the time finds true offshore flow. When a high-pressure ridge sets up and a sharp low tracks south, you get a short-lived blast of long-period W swell with light land breezes, turning Portsalon into a powerful, heavy playground for experienced surfers.

Low Surf Season (June - September)

Summer sees the North Atlantic energy dial way back. Average swell heights drop to 1.4-2.0m and periods fall below 10s, often producing small, weak, and wind-swell dominated waves. While the percentage of ideal offshore wind peaks at 39% in July and August, the lack of substantial swell direction from the east sector (only 1.9-2.6% combined) and the prevalence of choppy, short-period swell make for inconsistent, micro conditions. It's a flat spell punctuated by rare fun-sized days when a stray E swell coincides with a westerly breeze.

September: Autumn Reawakening

September marks the beginning of the autumn transition. Average swell height climbs to 2.0m and period rebounds to 10.1s as the Atlantic storm track activates. The dominant swell directions remain W (21.3%) and WNW (20.5%), but optimal E-sector swell increases to 2.6% (still low). Wind ideal percentage drops to 34% as early season lows bring stronger onshore flow. The key change is the increase in wave power. September delivers more consistent, solid surf—often in the head-high range—with occasional longer period swells. Wind direction is still wobbly, so you'll need to chase the clean slots between systems. When it all comes together, the waves have punch and shape.
