December: The Holy Grail of Swell and Offshore Wind
December is the standard by which the rest of the year is judged. The average swell sits around 7ft (2.1m) with a strong 12.8s period, and the direction mix is nicely spread between NNW at 35%, NW at 25%, and WNW at 9%. That broad W-NNW distribution means Sidi Ifni is constantly in the path of mid-winter North Atlantic storm swell, often with enough size to make things exciting.
The wind data makes it even better: ideal offshore conditions occur 40% of the time, the highest of any month. As Atlantic lows track past the region, colder air and shifting pressure gradients bring repeated windows of east, east-southeast, southeast and south-southeast flow. This offshore flow turns the northwest groundswell into lined-up, hollow waves along the exposed beaches. With air temperatures at 15.6°C, water at 17.9°C and moderate rain at 1.16mm/day, December is a true winter surf month - and the most consistent month of the year at Sidi Ifni.
