Conditions at Playa del Castillo in April
April: The Spring Transition Begins
April is a classic transition month at Playa del Castillo. Average swell height eases to 6.2ft (1.9m), but period drops below 11s to 10.9s, and the dominant swell direction shifts further north-NNW now supplies 47.3% of the wave energy, with NW at 16.7% and N at 12.2%. The true optimal W/WNW energy becomes scarcer. Meanwhile, NNE and NNW winds dominate at 36.8% and 18.4% respectively, while ideal wind windows fall to 13%, reducing the number of genuinely clean sessions. The surf is still rideable and punchy, especially on a high-tide push, but springtime winds make the window smaller. Water temperature climbs to 19.2°C, air averages 18.6°C, and rainfall is minimal at 0.18mm/day-a good month for those willing to hunt for the early-morning windows.
