Conditions at Carcavelos in July
July: Flat, Clean and Cruisy
July is the low point of the surf year at Carcavelos. Average swell height bottoms out at 1.3m (4ft) and period dips to 8.4 seconds - the shortest average of the year. The wave rose is split almost entirely between NW (43.4%) and NNW (42.7%), with WNW at 11.2%. There is virtually no S, SW or WSW swell to speak of, meaning the swell window is about as narrow as it gets. The waves that do show are short-period, mostly windswell, and often only groveling height.
Compounding the small surf is the wind: NNW dominates at an extraordinary 63.9%, with NW at 13.7%. This creates constant cross-offshore texture and limits the clean offshore windows. The ideal wind percentage falls to 37%, the lowest of the year. Yet summer still offers a handful of fun, small-wave days, often at dawn with a light N/NE breeze, high tide, and a waist-to-chest-high NW swell wrapping into the bay. Air temps average 20.0°C, rain is almost negligible at 0.11 mm/day and water temp is 17.5°C. Carcavelos in July is more about fun in the sun than heavy surf.
