Conditions at Foz in July
July: Peak Summer Doldrums
July is the slowest month of the year at Foz. The average swell height bottoms out at 0.8m (2.5ft), the period averages just 8.5s, and there is very little true groundswell. NNW (38%) and NW (34%) still dominate the direction data, but most of that is short-period, low-energy swell. The wind regime is the main spoiler: the Azores High sends a strong NE flow 27% of the time, with ENE adding another 16%; that puts the beach in a persistent onshore/cross-shore setup. Offshore SSW/SW flow only totals around 23%, and ideal conditions drop to 25%. Water temp hits 19.2°C and air averages 18.0°C, making the beach more of a summer social scene than a surf destination. When a rare longer-period NW swell filters in with a dawn SW offshore, the sandbars can wake up - but patience is required.
