Conditions at Prainha in July
July: Summer Doldrums
July is the low point of the Prainha calendar. Average swell bottoms out at 5ft (1.5m), period at 8.6s, and favorable wind percentage plummets to 7. The swell rose is almost entirely NNW (52.4 percent) and NW (31.7 percent), with most heights in the 3-5ft (1-1.5m) and 5-6ft (1.5-2m) bands. This is the classic summer windswell combo: plenty of lines but little push or definition.
The thermal-driven NNW 'nortada' blows 62.9 percent of the time, including a large share of 20-40kph breezes. With water at 18.1°C and air at 19.4°C, conditions are pleasant for beachgoers but marginal for real surfing. Only a freak tropical swell or a rare early-season low will inject any genuine size.
