December is the most consistent month of the year at Patos. The average swell is 5-6ft (1.7m), the average period is 12.6s, and the ideal wind frequency hits 43% - the best of any month. The swell rose is loaded with WNW (27.1%) and NW (16.8%), supported by W (16.3%) and WSW (9.6%), so the beach sees energy from every favorable quadrant. Offshore S/SSW winds (S 12.1%, SSW 7.7%) regularly team up with the long-period groundswell, producing clean, potentially heavy surf.
