Conditions at Airport in April
April: Trades Take Over
April marks the real beginning of Airport's prime season. The southeast monsoon locks in impressively: ESE dominates the wind rose at 32.8%, E follows with 19.1%, SE adds 13.0%, and ENE contributes 5.5%, producing a 72% ideal-wind score. For a west-facing beach this is pure offshore flow, grooming the face and holding the swell together. Average wave height holds around 5-6ft (1.7m), but the period jumps to 13.8s, and direction becomes heavily SSW at 65.4%, with S at 17.6% and SW still at 12.0%. The south-heavy angle means the swell needs to wrap a little, but the long period and clean easterly wind make it work.
Rainfall falls to just 4.36mm/day, air temperature is 25.6°C, and water temperature remains warm at 29.1°C. The wet season is clearly in retreat, and April offers a long stretch of semi-consistent overhead surf without the XL sizes of mid-winter. It is an excellent month to be at Airport.
