Conditions at Castaways in April
April: Transition and Tradeoffs
April is a month of changing seasons. The northeast monsoon is fading, and the winds start to swing to WSW and W, signaling the approach of the southwest monsoon. Ideal offshore flow occurs just 35% of the time, and the onshore afternoon patterns become a recurring challenge. The swell, though, is still very much alive. Average height climbs to 1.3m (4.5ft) with a 11.6s period, and S (41.5%) plus SSW (22.3%) dominate the spectrum. When conditions align - typically in the early morning - Castaways offers hollow, long-period walls that are well worth the paddle. But be prepared for wind-affected waves as the day progresses. Water temperature reaches 30.1°C, and precipitation increases as the monsoon transition kicks in.
