April: The Monsoon Cusp Brings Size
April is a transition month, with the northeast monsoon beginning to break down. The average swell height rises to 1.3m (4.3ft), and the period reaches 11.6s - the highest average of the year. The swell direction now becomes overwhelmingly south: S (44.1%), SSW (22.0%), SSE (19.9%), with a nice chunk of SW (8.4%) creeping in. The SSW and SW energy is a hint of the coming southwest monsoon. On the wind side, the offshore W/WNW quadrant actually strengthens nicely: W (22.5%), WSW (19.6%), WNW (16.0%), plus NW (6.9%) - this keeps the ideal wind percentage at a solid 53%. So April offers a unique mix: bigger, longer period S/SSW swells groomed by offshore westerlies. Air temperatures are 28.4°C (26.0-30.3°C), precipitation 4.19 mm/day, and water temperature 30.0°C. When the sea breeze doesn't kick in too early, you can find powerful 4-6ft (1.3-1.8m) reef waves.
