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.

January: Big West Swells, Tough Orientation

January roars with an average swell height of 3.2m and a long period of 12.4s—classic North Atlantic muscle. The vast majority of this energy arrives from the W (12.5%) and WNW (8.4%), which means most waves are approaching from the far left, creating a tricky, shifty lineup for the NE-facing beach. The optimal swell directions (NNE to E) barely register a combined 2.2%. On the bright side, offshore wind from the SSW-SW sector is reasonably prevalent (SW 12.3%, WSW 11.9%), giving you a clean face when the swell lines align. With ideal wind only 26% of the time, you'll need to pick your windows carefully, but when a depression tracks just right, you get powerful, hollow waves that demand respect.
