April: Cleaner Windows and Springtime Potential
April brings the first real taste of spring and a gradual easing of the winter fury. Average swell height drops to 1.4m (4.5ft), with period down to 10.3s - still more than enough for a top-tier reef. The swell direction distribution is hugely favourable: NNW accounts for 18.4%, WNW 20.3%, NW 9.7% and W 12.5%, while north and NNE sectors add another 9.9%. Combined, the optimal northern window is over 38% of observations, the highest of the year. Heights are more concentrated in the 0.5-1.5m range, producing fun, powerful and rippable conditions rather than constant bombs.
Wind patterns also improve slightly: ideal S/SSE/SSW offshore winds total 31% of the time, and SE winds are the most frequent single wind sector (12.6%) after the stronger westerlies fade. Air temperature rises to 6.7°C (44°F), water is still a chilly 7.8°C (46°F), and precipitation falls to 2.23 mm/day. April is a prime month for those who want quality without the relentless intensity of deepest winter.
