Conditions at Cabedelo do Douro in August
August: Late Summer Doldrums, Lingering Possibilities
August is statistically just as small as July, with average swell height of 3ft (0.9m), period of 9.0s and ideal winds only 13 percent of the time. The direction mix remains favourable in name only: NW 51.0 percent, WNW 40.2 percent and W 6.4 percent. But these are almost entirely low-energy, short-period NW windswells - rideable on a log but rarely enough to make Cabedelo's shifting sandbanks light up.
The wind regime continues to blow from the northwest quadrant, with NNW at 42.2 percent and NW at 16.1 percent. Occasional early-season Atlantic pulses can sneak in by the end of the month, and if an easterly wind lines up with one of those pulses, Cabedelo can still produce clean, playful waves in the 3-5ft (0.9-1.5m) range. Air temperatures are at their warmest around 20.4°C, the Atlantic is 16.9°C, and rainfall is minimal at 0.75mm/day. Keep the longboard in the car.
