Conditions at Cabedelo de Viana in August
August: Smallest Swell, Cleanest Wind
August mirrors July with a 1.4m (4.6ft) average swell and a 9.0s period, but it has the year's best wind consistency: 63 percent ideal conditions. The swell rose is still all about the northwest, with NW 39.6 percent, NNW 32.4 percent and WNW 18.9 percent making up virtually the entire surf supply. Most days offer small, clean waves in the 0.5-1.5m (2-5ft) range, fun-sized and rippable, with the occasional summer pulse of longer-period NW energy pushing into overhead territory on the better sandbars. Water temperature is 16.8°C, air temps around 20.9°C, and rain is minimal. The trade-off for small surf is excellent surface conditions - during the early morning, offshore winds and smooth ocean surfaces can make the tiny waves feel twice as good. It is the classic summer surfing month in northern Portugal.
