Conditions at Cotton Trees in April
April: Southern Groundswell Gains Traction
April sees the average swell height climb to 3-4ft (1.1m), with the period stepping up to 11.8s. South swell now dominates forcefully at 70.4%, and a healthy 42.6% of all readings fall in the fun 3-5ft (1-1.5m) range; another 0.9% reaches 5-6.5ft (1.5-2m). SSW supplies 29.1%, with 22.6% in the 3-5ft class and 1.6% in 5-6.5ft. This is more legitimate surf. The problem remains wind: ideal conditions are only 10% of the time, and WSW (22.5%), W (16.2%) and SW (17.2%) keep a frequent onshore texture. On the bright side, the wet season is just starting (2.61mm/day) and water temperature is 28.0°C, so if you catch one of those clean mornings, it will feel tropical and punchy. Air temps stay near 27.4°C.
