April: Transition Mode and Long Grinding Lines
April is a pivot month. The average period jumps to 13.8 seconds, giving the swell real depth, and the SSW direction accounts for 73.7% of the energy with S adding another 11.4%. Average height remains a manageable 5ft (1.5m), mostly in the 4-6ft (1.2-1.8m) range. The catch is wind: ideal conditions drop to 30% as ESE and SE trades begin to strengthen. Early light-wind windows, especially around dawn, still serve up long-period reef waves, but afternoon southeasterlies can crumble faces. Air temps are 27.7°C, water temperature 29.4°C, and rainfall drops to 4.06mm/day.
