January: Winter Mix of Offshore Winds and Southern Pulse

January at La Bocana is all about trade-offs. The average swell height sits at 4.6ft (1.4m), with an average period of 11s, which puts it in the powerful long-period class for this stretch of Mexican coastline. The swell direction is a genuine split personality: NE/ENE swells account for about 35% of the energy, while the more favorable S/SSW/S directions combine for just over 44%. That means the waves at the beach are often a blend of shorter-period NE windswell and cleaner S/SSW groundswell. When the S/SSW component takes over, the south-facing beach lines up properly; when the NE energy dominates, expect more sectiony, cross-up peaks. The good news is that winds are favorable 54% of the time. N/NNE/NE flow is common (NE 20.5%, NNE 15.1%), and the S/SW onshore directions stay relatively weak. With water temperature at 26.3°C and only 0.12mm/day of rain, January is a dry, warm month-so winter surfers can enjoy clean 3-5ft (1-1.5m) sets with occasional 6ft (1.8m) bombs, especially around dawn.
