Conditions at Spot Kontiki in April
April: Autumn's Bigger, Heavier Southern Swell
April marks the true autumn transition. Average swell jumps to about 5-6ft (1.7m) and the average period reaches its annual peak of 13.6s, so there is no shortage of power. However, the direction becomes much more locked into the SSW: 92% of the recorded swell is from that direction, with only 5% from the preferred SW window and no meaningful WSW/W/WNW energy. This is the catch at Kontiki: the ocean is producing serious groundswell, but much of it is angled away from the beach's optimal exposure. The wind remains tricky, with S and SSW winds totaling around 60%, though ideal offshore conditions still occur about 13% of the time. When those rare offshore east/northeast mornings align with the 13.6s SSW swell, expect well-refracted, powerful sets. Water temperature drops to 17.5°C, air averages 19.9°C, and rainfall is minimal.
