Praia da Rocha - surf spot statistics

Best Surf Season (October - March)

This is prime time for Praia da Rocha. The North Atlantic storm track is active, consistently sending long-period swell toward the Algarve. Average wave heights range from 1.1m to 1.4m and periods from 11.1s to 12.9s, offering powerful, well-formed waves. Offshore wind frequencies peak during these months (37-43%), with northerly and northeasterly flows providing clean grooming. While the dominant swell direction is often from the northwest, it refracts into the beach and combines with occasional direct southwesterly swell for variety. Expect consistent surf with plenty of head-high to overhead sets.

Fair Surf Season (April - June & September)

Transitional months bring a mix of conditions. Swell energy decreases from winter's peak, with average heights dropping to 0.8-1.1m and periods shortening to 8.9-10.8s. Offshore winds are less frequent (28-37%), but still occur often enough for clean sessions, especially in the mornings. This is the time for smaller boards and groveling when the swell is low, but occasional late-season or early-autumn storms can still deliver fun, rippable waves. September sees a notable uptick in period and offshore wind percentage as the Atlantic comes back to life.

Low Surf Season (July - August)

Summer is the quietest time for surf. Average wave heights drop to 0.7-0.8m with short periods around 8-8.6s, resulting in small, weak surf. The dominant swell comes from the NW and NNW but lacks the power to wrap effectively. Offshore wind percentages are the lowest of the year (27-30%), and the reliable northwesterly winds often have a cross-shore component. Expect small, fun-sized days suitable for longboards or soft tops, but don't expect pumping surf. Early mornings offer the best chance for clean conditions before the sea breeze kicks in.

August: Faint Signs of Life?

August remains small, with average swell height of 0.7m and period of 8.6s – still very much the summer doldrums. The swell direction is again dominated by NW (59.1%) and WNW (23.6%), but a slight uptick in longer-period 10-14s swell begins to appear later in the month. Offshore wind probability climbs slightly to 30%, with N (8.0%) and NNW (30.4%) being the main players. However, NNW wind here is still not perfect; it's better than onshore S-SW winds which are rare. The wind rose shows that NW winds (21.5%) still blow cross-onshore. Swell heights: 73% in the 0.5-1m range, 22% in 0-0.5m – tiny. The good news is that August often sees the first distant hurricane swells or early-season low-pressure systems that can send a few pulses of longer-period swell. The period average of 8.6s is still short, but occasional 10s+ waves can appear. Don't get your hopes up – August is a month for flat spells punctuated by small, clean windows. Those windows are worth pursuing if you're a longboarder.
