Conditions at Sun Beach in April
April: Grovel Season Takes Hold
April marks the true transition to small surf. Average height falls to 1.2ft (0.4m), the period drops to 4.1 seconds, and the percentage of favourable N/NNW energy above 0.5m drops sharply to under 5% of the total spectrum. ENE swell dominates with 38.5%, followed by NE at 17% and E at 12%. For an NNW-facing beach, that means the swell is arriving mostly from directions that are either cross-shore or shadowed by the coastline, producing weak, sectiony waves.
The wind field is locked into the spring trades: ENE 23%, E 22% and ESE 14%, with strong 20-40kph pulses common. Offshore south/southwest winds are present only about 7% of the time. Expect warm, humid air near 27°C (81°F) and water at 26°C (79°F), with a rise in precipitation to 1.05 mm/day. April is longboard-only territory at Sun Beach, and even then, the lack of period and prevalence of cross-shore drift will keep scores low.
