Reef seasonal overview
The best months for surfing at this reef break in Portugal are from October through March, with peak conditions typically occurring in January, February, and December. During these months, ground swell dominates (74–91%), ensuring powerful, well-organized waves, while wind swell plays a minor role. Average swell heights range from 1.9 to 2.2 meters, offering solid overhead waves suitable for experienced surfers. Wind conditions are also more favorable in these months, with good offshore or light onshore winds occurring 27–34% of the time, though unfavorable winds remain prevalent (66–73%). The winter season provides the most consistent and highest-quality surf, with December and January being particularly reliable for clean, large swells. Spring (April–June) and summer (July–September) see a decline in ground swell influence, shifting toward wind swell dominance (59–83%), which results in smaller (1.1–1.7m) and less consistent waves. Wind conditions worsen significantly in these months, with bad winds affecting 80–89% of days, often creating choppy or onshore conditions. While September and October mark a transitional period back to better surf, November stands out as the first month of the winter season with improving consistency. Overall, advanced surfers should target the winter months for the biggest, cleanest waves, while summer is best for beginners or those seeking smaller, more forgiving conditions.

Conditions at Reef in January
January at this reef break in Portugal offers consistent, powerful surf with an average swell height of 2.2m and a solid 12.9s period, indicating well-organized, energy-rich waves. The predominant swell direction is WNW (38% of waves in the 1.5–2.5m range), delivering clean, lined-up walls ideal for advanced surfers. WSW and SW swells also contribute, adding variety but with slightly less consistency. Wind conditions are surfable 34% of the time, most frequently light to moderate (10–30kph) from the N-NW quadrant, which can create offshore or cross-offshore effects. However, stronger winds (>20kph) from the N/NE occur ~10% of the time, potentially causing choppiness. Expect bigger days (2.5m+) on 9% of swells, mainly from W-WNW—best for experienced riders. Smaller, manageable waves (1–1.5m) appear 26% of the time, often with lighter winds. Overall, January delivers reliable, high-quality surf but demands skill to handle the size and occasional wind challenges. Prioritize WNW swell windows with NW winds for optimal sessions.
