Conditions at Sosua in April
April: The Trade Swell Takes Over
April signals a noticeable shift. Average swell height drops to 4.3ft (1.3m) and period backs down to 8.9s, while the optimal N/NNE/NNW quadrant falls to 14.5% of the wave rose. The spotlight now moves firmly to ENE (41%) and NE (30%) swells, which hold the beach up but lack the direct, open-ocean power of winter N/NNW pulses. Ideal winds improve slightly to 35%, and the ESE/SE trades are less aggressive, leaving waist-chest-high waves looking clean and fun. Air temps begin to warm with an average of 25.4°C, while water temp stays pleasant at 26.3°C. This is a good month for longboarders and groovellers; shortboarders should pick the days when a late-season cold front adds a few extra seconds of period.
