Conditions at Cabedelo do Douro in July
July: Peak Summer Flatness
July represents the lowest point of the surf year in terms of size and period. Average swell height is just 3ft (0.9m), average period 8.8s, and the wind is ideal only 11 percent of the time. Swell direction is almost entirely from the northwest quadrant, with NW 51.8 percent and WNW 40.8 percent, yet these waves normally arrive as weak, short-period windswell from the same Azores High / nortada pattern that creates summer's persistent north wind.
Indeed, NNW wind reaches 43.2 percent and NW 16.1 percent, so the daily afternoon sea breeze is more often than not an onshore/cross-shore mess at the Douro mouth. The few clean sessions happen in the early morning, before the wind fills in, when the tiny waist-to-shoulder-high waves can still offer fun turns on the sandbar. Air temps average 20.1°C, water 16.8°C, and precipitation is almost negligible at 0.41mm/day. Bring the summer boards and keep expectations low.
