Conditions at Espinho in July
July: Peak Summer Flat-Spell Potential
July is usually the slowest month of the year at Espinho. The average swell height bottoms out at 3ft (0.9m), and the average period at 8.8s, right on the edge between junk windswell and rideable, small-wave conditions. Swell direction is overwhelmingly from the northwest quadrant, with NW at 51.8% and WNW at 40.8%; pure W swell has shrunk to just 5.2%. Most of the energy is a mix of short-period northwest windswell and weak groundswell moving through a subtropical high-pressure regime, producing small, soft, often crumbly surf.
Winds are even less favorable than June, with ideal conditions just 11% of the time. The thermal northerly becomes relentless, with NNW wind at 47.0% and NW at 15.1%, blowing most of the day and keeping the surface lumpy. Offshore E and ESE winds are rare but magical when they arrive, often setting up clean, longboard-friendly lines on a smaller scale. Air temperatures peak around 20.1°C, water temperature is 16.9°C, and rainfall is minimal at 0.41 mm/day. This is the season for funboards, loggers, and seafront cafes, not for expecting firing Atlantic surf.
