Conditions at Praia da Rocha in April
April: Shoulder-Season Swell with Clean Windows
April marks the first noticeable downshift in energy. Average swell height drops to 3.6ft (1.1m), and the average period slips to 10.8s. WNW (32.6%) and NW (25.5%) remain the dominant directions, but the direct S-SSW-SW-WSW window is still present at just under 11%, enough to make the beach light up when a late-season storm brushes by. The northwesterly wind regime becomes more pronounced: NNW wind is the single largest wind direction at 22%, while ideal offshore N-NNE-NE-ENE wind drops to 31% of the time. This means more sideshore texture, but the water temperature is rising to 16.4°C and air temperature to 15.8°C. With 2.03mm/day of rain and plenty of spring weather swings, April remains a gamble - but a good gamble for clean, fun surf.
