April: Groundswell Season Begins
April is where the quality curve really bends. Average swell height reaches 5ft (1.5m), average period climbs to 9.4s, and ideal wind windows expand to 29%. The swell rose is much better balanced: S swell doubles to 13.7%, SSE contributes 18.1%, and SE 20.6%. This is the month when proper south groundswell - generated by mid-latitude cyclones off Argentina - starts showing up between the easterly windswell.
On the wind side, NE flow still dominates at 22.7%, but the onset of stronger SSW/SW wind sectors and the increase in W/NW offshore mornings mean cleaner, more organized conditions. Water temp remains pleasant at 22.6°C and air temps dip to 21.7°C. April is a strong 'shoulder-plus' month, with standout days often producing chest-to-head-high, lined-up surf.
