Conditions at Pedra Branca in April
April: Transitional Mix of Heavy Groundswell and Spring Breeze
April is a transition month, but the ocean still has winter in its bones. Average wave height remains a respectable 6-7ft (1.8-2.1m), and the period falls only to 11.1s - enough for powerful, long-period lines. Swell direction is dominated by NW at 28%, with WNW and NNW also contributing big percentages; Pedra Branca continues to see excellent open-ocean exposure, though wave heights are now more concentrated in the 5-8ft (1.5-2.5m) band and the oversized 8ft+ (2.5m+) days become less frequent.
The main issue in April is wind. Ideal conditions drop to 13%, and true offshore flow from the east and southeast is rare, barely 8% of the time. The spring nortada starts to bite, with NNW winds at 28.6% and additional NW and N flow, creating a lot of cross-shore and onshore conditions. Air temperatures warm to 14.7°C, water to 15.7°C, and rainfall remains moderate at 1.88mm/day. If you can find the occasional east-wind window, especially during a high-pressure reset, April can still serve up punchy, lined-up waves at Pedra Branca.
