Sao Pedro de Moel - surf spot statistics

Best Surf Season (October - March)

The heart of winter unleashes its full fury upon Sao Pedro de Moel, with the North Atlantic pumping out consistent, powerful swells from the NW to WNW quadrants. Average heights hover around 2m to 2.4m, with long periods often exceeding 12 seconds, delivering heavy, grinding peaks. Offshore wind frequencies peak during this period, especially in December (37%) and January (36%), as high pressure systems settle over Iberia, funneling clean east to southerly breezes. This is prime time for experienced surfers to charge the sandbars.

Fair Surf Season (April & September)

Transition months bring a mix of leftover winter energy and early autumn pulses. April sees average swell heights drop to 1.8m with periods around 11s, while September picks up again to 1.5m and 10.5s. Ideal wind frequencies drop to 20% and 17% respectively, as the Azores High begins to influence the region, creating more variable winds. While not as consistent, these months offer cleaner conditions on the right synoptic setup, often with smaller but rippable waves.

Low Surf Season (May to August)

Summer is a quiet period for this exposed W-NW facing beach. Swell heights shrink to a meager 1.3-1.5m, with periods dropping below 10 seconds. The dominant wind shifts to a persistent NW to N regime, which blows directly onshore at Sao Pedro, chopping up what little swell there is. Ideal offshore wind frequencies plummet to single digits (5-9%), making clean surfing sessions a rare luxury. This is the time for flat spells, groveling smaller boards, or seeking shelter elsewhere.

March: Late Winter Pull

As winter transitions, March still packs a punch with average swell heights of 2.1m and periods of 12.4s. The dominant swell shifts slightly more toward NW (27.6%) and WNW (23.0%), while N winds become more common (18.6% overall). Ideal wind frequency drops to 27%, with offshore breezes favoring the S/SW quadrants. The longer days add light and warmth, but the Atlantic remains active — expect solid, long-period swells mixed with occasional onshore wind chop. This is a 'solid' month for experienced surfers, though shorter interval windswells can creep in.
