Cabo Blanco - surf spot statistics

Best Surf Season (January - April)

The first four months of the year deliver the most consistent offshore winds at Cabo Blanco, with ideal conditions blowing from the S, SSW, and SW over 50% of the time. Average swell heights hover around 1.5-1.7m with long periods of 14s, providing a solid, rippable wave face. Even though the dominant swell originates from the SSW and SW rather than the optimal NW quadrant, the long period allows for good refraction into the NW-facing beach. The result is clean, powerful surf that is both fun and challenging – the sweet spot of the year.

Fair Surf Season (May & December)

May brings a jump in average swell height to 1.8m, but the ideal wind percentage drops to 43%. Stronger S and SSW winds (often 20-30kph) create more texture on the faces, though occasional lighter days still produce good waves. December sees a similar pattern: average swell 1.6m, ideal wind 38%, with a mix of SW and WSW swell. These months offer decent waves if you can pick your windows carefully.

Low Surf Season (June - November)

From June through November, the robust Southern Hemisphere swell machine pumps out consistent 1.8-1.9m groundswell with long periods, but the wind regime turns against the spot. Ideal offshore wind percentages plummet to 19-28%, with persistent moderate to strong S and SSW winds (often 20-30kph) that chop up the surface. While the swell is powerful, the lack of clean, light offshore flow means most days are disappointing. Occasional high-pressure setups can align the winds from the SSW, offering brief but brilliant sessions – but expect to work for them.

July: Winter Swell Peak, Wind Struggle

July sees the same average swell height of 1.9m with a period of 13.8s. Swell is still dominated by SSW (88.2%), with S (5.1%) and SW (1.9%). Over 52% of waves are 1.5-2m, and 24.6% in the 2-2.5m range – XL potential when conditions align. However, ideal wind percentage hits a low of 22%. Winds from S (47.3%) and SSW (32.9%) are often strong (20-30kph for S at 32.8%, SSW at 16.8%). This creates messy, blown-out surf for the majority of the month. The few days with lighter SSW wind can produce epic, glassy waves, but they are rare. Patience is key.
