January: Winter Groundswell Meets the Trades
January is the heart of Sosua's winter season. Average swell height sits at 5ft (1.6m) and average period is 9.4s, with the optimal N/NNE/NNW combination making up around 20% of the wave rose. The overall picture is dominated by ENE and NE swell - together about 63% - but those directions are not the beach's ideal window. The real magic happens when a Nor'easter or North Atlantic low aims a long-period N/NNE swell at the north coast while the trade swell adds background energy. Winds are ideal 34% of the time, with E/ESE trades at 10-30kph being the main influence; they blow cross-offshore and can keep lines clean, but a true S/SW offshore flow is what really turns the beach on. Water temp is 26.5°C, air temp averages 24.7°C, and rainfall is light at 1.6mm/day. Pick your windows around the morning glass-off and January will not disappoint.
