Pedrogao seasonal overview
Best Surf Season (October - March)
The North Atlantic roars to life during these months as the polar jet stream drives a relentless procession of extratropical storms across the basin. Pedrogao, with its west-facing exposure, captures the full force of long-period WNW to NW groundswells — the average height hovers between 2.0-2.5m and periods stretch to 11-13s, providing powerful, well-formed waves. A positive NAO phase often amplifies this activity, yet it also increases the frequency of onshore west winds. However, when high pressure ridges into the Bay of Biscay, it funnels offshore winds from the east and southeast, creating pristine conditions. The ideal wind window remains open 25-34% of the time, making these months the most reliable for quality surf.
Fair Surf Season (April, May, September)
As the ocean transitions from winter fury to summer calm, the swell pulse becomes more inconsistent. April and September still benefit from occasional long-period NW swells that break in the 1.5-2.0m range, with periods around 10-11s. The ideal wind frequency drops to 18-19%, but when the right synoptic setup aligns — a lingering Azores high or a passing cold front — the surf can be clean and rippable. May is a step down: average height falls to 1.5m with 10s periods, and favorable winds only occur 14% of the time. These months are best for those willing to gamble on a good day rather than a consistent season.
Low Surf Season (June - August)
Summer settles in and Pedrogao slips into a classic Mediterranean-style lull. The dominant swell shifts to short-period, locally generated NW windswell, averaging just 1.3-1.4m with 8.7-9.3s periods — often small, weak, and easily chopped by the persistent NNW and N winds that blow over 60% of the time. Ideal offshore conditions are a rarity, occurring only 5-9% of the entire season. The waves rarely exceed 1.5m, and when they do, they are usually accompanied by onshore winds. Unless you’re a beginner or desperate for a paddle, these months are best spent exploring other corners of the world.

Conditions at Pedrogao in December
December: Winter Foundation
December solidifies the winter peak with an average swell height of 2.3m and 12.7s period. Swell arrives from a broad range of optimal directions: NW (24.1%), WNW (20.6%), W (8.0%), and a growing contribution from WSW (3.4%). The height distribution shows a healthy chunk of surf in the 1.5-2.5m range, with some waves exceeding 2.5m, providing challenging, heavy conditions for advanced surfers. Ideal wind is at its highest for the year, tying January at 34%. The wind rose indicates a greater mix of offshore directions (ENE through SE) and a reduction in the strong northerlies that plague summer. As low-pressure systems barrel across the Atlantic, Pedrogao reaps the rewards. This is prime time for those seeking consistent, high-quality winter surf.
