Patos - surf spot statistics

Best Surf Season (October - March)

The North Atlantic roars to life as autumn deepens into winter, delivering consistent, powerful groundswell to Patos. Average swell heights range from 1.3m in October to 1.8m in January, with long periods of 11-13 seconds offering punchy, well-organized waves. The dominant swell directions of WNW, NW, and W align perfectly with the spot's NNW exposure, while offshore winds from the S to SW quadrant blow cleanly over the beach 37-43% of the time. This is prime time for pumping, firing surf, with frequent 1.5-2.5m sets and occasional XL waves when strong Atlantic storms line up. The combination of long-period energy and favorable wind is the recipe for Patos at its best.

Fair Surf Season (April & September)

Transition months bring a noticeable drop in average swell height to 1.3m in April and 1.0m in September, with periods averaging 11.0s and 10.5s respectively. Despite the smaller size, the quality remains high when conditions align. WNW and NW swells still dominate, but the frequency of offshore winds decreases to around 30-31%. Clean, rippable waves in the 1-1.5m range are common, and occasional pulses from late-season storms can deliver fun-sized surf. These months are a mixed bag, but patient surfers are rewarded with glassy mornings and manageable crowds.

Low Surf Season (May - August)

Summer settles in with a pronounced lull in swell energy. Average wave heights drop to 0.8-1.0m and periods shorten to 8.7-9.9s, resulting in weaker, more wind-affected conditions. The predominant swell still comes from the NW quadrant, but large percentages of small, choppy surf (<1m) dominate. Offshore wind occurrence plummets to 17-25%, as the prevailing synoptic pattern brings more onshore winds from the N and NW. When a rare summer storm track delivers a pulse of W or SW swell, the offshore S winds can align for brief windows of clean, fun-sized surf. But for the most part, expect groveling conditions—a time for longboards and low expectations.

July: Peak Summer Slump

July is the absolute low point for surf at Patos. Average swell height is just 0.8m with a period of 8.7s—the smallest and weakest month. Swell direction is dominated by WNW (30.0%), NW (26.5%), and NNW (23.6%), but 95% of waves are below 1.5m, with most under 1m. Offshore winds blow only 17% of the time, the lowest of the year, as the predominant winds are onshore from the N and NW. The rare swell pulse from a tropical storm or distant low can produce a short burst of rideable waves, but these are exceptions. Summer is the time for flat spells, socializing, and enjoying the beach—not for serious surfing. Patos is essentially flat or close to it for long stretches.
