Conditions at Costa Nova in July
July: Peak Summer Malaise
July is the slowest month of the year at Costa Nova. Average swell hits its annual minimum of 1.4m (4-5ft), with periods averaging only 8.6s, and the swell direction is almost exclusively from the NW (45.4 per cent) and NNW (34.1 per cent) quadrants. Most of this is short-period, locally generated windswell, punchy and rideable on the sandbars when clean, but rarely with the consistency or power to get the heart rate up.
Offshore wind is a rare commodity, clocking in at just 9 per cent, the lowest of the entire year. The NNW trade wind blows 50.1 per cent of the time, and onshore W/NW components add occasional lumps. Water temperature holds at 17.7°C and air averages 20.8°C, making it pleasant in the water, but you will need a groveler mindset and a flexible schedule. The best bet is early morning before the wind peaks, or a solid SE offshore flow ahead of a rare summer thunderstorm.
