December: Dry-Season Return and Maximum Offshore Reliability
December is the cleanest month at Ciruelo by wind statistics - an excellent 80% ideal-surfing conditions. The trade wind regime is fully reestablished, with NNW supplying 41% of the wind and N/NNE together adding another 34%; offshore flow is the rule rather than the exception. The average wave height dips slightly to 1.0m (3.2ft) and the period shortens to 10.3s, so the power is less dramatic than the 14s southern-swell months, but the surfaces are far more groomed.
In the swell rose, SSW at 38% and SW at 14.9% still provide the best lines, while a decent amount of northern N/NNE/NNW energy mixes in and creates a punchy, variable winter beachbreak. Rain drops to 4.82mm/day and water temperature is still a warm 28.0°C, making December an extremely pleasant, user-friendly month: smaller but consistent, clean and very surfable.
