Conditions at Herradurra in July
July: Mid-Winter Muscle
July is one of the least consistent months for wind at Herradurra, with ideal conditions only 75 percent of the time. The S wind regime dominates at 83.3 percent, and 20-30kph winds become a major feature at 21.2 percent, with the first hints of 30-40kph flow in the mix. The stronger southern trades create more bump and chop, so wave quality becomes more session-dependent.
The ocean, however, is full of energy. Average wave height remains at 5ft (1.5m) with a 13.0s period. SSW swell accounts for 83.8 percent, while S swell grows to 7.3 percent and SW adds another 8.2 percent. The distribution is heavy-39.5 percent of waves are in the 5-7ft (1.5-2m) range and 9.2 percent reach 2-2.5m (6-8ft). When the wind does ease, the power is outstanding. Water temperature drops to 16.7°C and air averages 16.7°C, so this is winter surf in the truest Peruvian sense.
