July: Mid-Winter Rhythm
July keeps the winter momentum going. The average swell height is 1.6m (5-6ft), the average period is 9.4s, and the wind is ideal 51% of the time. Swell directions are a little more mixed than June, with east-northeast at 16.7%, east at 14.1%, south at 15.8% and south-southeast at 13.5%. This means Prainha still sees plenty of energy, though some of the more easterly pulses arrive with less direction efficiency. The northeast trade wind picks up a bit at 12.6%, but the west through northwest offshore quadrant remains strong, keeping many days clean. Water temperature drops to 16.2°C and air temperatures sit around 13.6°C, making it proper winter surf. July offers quality, but the best days are tied closely to cold-front passages.
