Conditions at Serangan in April
April: Bigger Swell, Under Pressure
April marks the real transition into the East Monsoon. Average swell height nudges up to around 5-6ft (1.5-1.8m) and the period jumps to 13.8s, with SSW swell now contributing 65.4 percent of the total and S adding another 17.6 percent. The good WSW/SW window is still a factor at 12.2 percent, but the wind turns onshore: E, ESE, and SE combine for nearly 65 percent of the wind while ideal offshore W/NW flow collapses to 19 percent. What you get is size and power, but also bump and chop on the surface unless you time a dawn or transitional window. Water temp stays at 29.1°C with air temps around 25.6°C, and precipitation falls to 4.36 mm/day. April is the tease of the year - the swell is firing, but the trades are itching to ruin the party.
