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.

July: Clean and Small

July offers the highest ideal wind percentage of the year at 39%, with a strong offshore component from the WSW (12.4%) and W (12.2%) directions. This means a lot of groomed, glassy surface conditions. Unfortunately, the swell size is minimal—1.4m on average—and period drops to 8.6s. The optimal NE swell sector totals a mere 1.9%, the lowest of spring. The dominant swell comes from the W (29.4%) and WNW (26.5%), but these are often weak, short-period waves. July is a great month to practice, but you'll be scratching for wave height on most days. Look for rare tropical storms or distant lows to boost the energy, but don't hold your breath.
