April: Long-Period SSW Groundswell Hits Full Stride
April is where Petacalco starts to fire. The average swell jumps to 1.3m (4.3ft), the average period reaches 14.0s, and a remarkable 78.5% of the swell arrives from the SSW. Combined with 19.9% from SW, this is essentially a pure south-groundswell month. Nearly 80% of waves fall in the 1-1.5m (3.3-4.9ft) solid, rippable range, plus a meaningful 11.4% of 1.5-2m (4.9-6.6ft) pumping sets. Winds are ideal about half the time; expect SW/SSW afternoon seabreezes to deteriorate conditions, so chase the early-morning offshore W/NW window. With just 0.03mm/day rain, air temperatures averaging 26.7°C, and water at 27.6°C, April offers dry, warm, high-quality surf.
