Conditions at Portsalon in July
July: The Smallest but Cleanest Swell
July marks the low point for Portsalon's surf size: the average swell height bottoms out at 1.4m (4.6ft) and the period at 8.6s. The W and WNW swell sectors combine for a huge 56% of observations, but the vast majority is soft 1-1.5m (3-5ft) surf from the summer Atlantic. The optimal NE/E window is at its smallest of the year, just under 2%, meaning truly good Portsalon direction is rare. Yet offshore SSW-SW-W winds blow 39% of the time - the best of the year - so when any small NE-E swell appears, it can be smooth, clean and playful. Water temperature reaches a summer high of 15.3°C, air averages 14°C, and occasional showers (3.5mm/day) are typical. This is longboard and midsummer fun-surf territory.
