August: Cool Water, Heaving Sets
August is the climatological heart of the Peruvian surf season. Average swell height matches the winter peak at around 6.2ft (1.9m), and the 13.8-second period means every set has real push. The SSW direction is responsible for 89% of the total swell energy, with S adding 4% and SW 2%. Over half of the observations are in the 5-6.5ft (1.5-2m) range, and 26% reach the 6-8ft (2-2.5m) bracket. This is the kind of steady, heavy groundswell that makes a surf trip worthwhile.
Wind consistency is slightly lower than June but still strong at 71% ideal. The wind rose shows a very clean SSW/SW/WSW regime, with SW the single largest source at 29%, and a healthy chunk of that blowing at 10-20kph. Air temperatures are the coolest of the year at 20.9°C, and water temperature bottoms out at 19.6°C. Precipitation is essentially zero. August is all about cold mornings, neoprene sessions and long, grinding waves.
