Conditions at Prainha in April
April: The Shoulder Season Shuffle
April is a true transition month. Average swell height drops to 7ft (2.1m) and the period shortens to 11.2s, so there is less of that ruthless North Atlantic push. Directionally, NW (25.1 percent), NNW (19.8 percent) and WNW (19.7 percent) are almost evenly split, and the height distribution emphasizes 5-6ft (1.5-2m), followed by the 3-5ft (1-1.5m) and 6-8ft (1.8-2.4m) classes. The surf at Prainha remains rideable, but the mixed NW/NNW angle means being selective with tide and lineup position.
Only 23 percent of the winds are ideal, and NNW wind becomes the dominant summer-style influence at 29.4 percent. Air temperature is 14.5°C, water is 15.3°C, and precipitation is 2.08mm/day. Good days exist, but the windows are shorter and the margin for error grows.
