Conditions at Assinie in July
July: Heavy Water, Heavy Wind
July delivers the largest average swell of the year alongside June and August: around 4ft (1.3m) at 11.6s. The S/SSW split is 65.2% and 34.6%, a slightly broader angular spread that adds some SSW juice. There is also 9.7% from S and 4.8% from SSW in the 5-6.5ft (1.5-2m) bracket, so the set size is real. But the onshore wind statistics are brutal: SW wind jumps to 44.6%, with 26.4% blowing 10-20kph, and SSW adds another 31.4%. Ideal wind drops to just 1%.
This is the heart of the cold-water upwelling season. Water temperature drops to 25.0°C, air temperature to 24.9°C and rainfall decreases to 3.36mm/day. The surf is heavy and often unruly, with a lot of raw power. This is a month for keen local chargers, not for beginners, unless you find a clean window.
