Conditions at Matadouro in July
July: Mid-Summer Lull
July is the toughest month of the year for consistent quality at Matadouro. Average swell height is only around 4.5ft (1.4m) and the average period is 8.5s, the shortest of the year. The wave direction stats are staggering: NNW supplies 54.2% of all swell, with NW at 33.0% and WNW at 9.2%. What little energy arrives is mostly short-period, locally generated north windswell rather than real Atlantic groundswell.
Ideal offshore wind is essentially non-existent - only 3% of the time. The infamous summer northerly dominates at 59.4% of wind observations, with N (13.0%) and NW (9.0%) strengthening the pattern. A fresh-to-strong NNW wind blows all day, leaving the surf bumpy, wobbling and hard to ride. The few good windows come with a dawn glass-off and a favorable east wind, usually tied to a heat low over the Iberian Peninsula.
Water temperature is 17.4°C, air temperature averages 20.2°C, and precipitation is minimal at 0.15mm/day. A 3/2mm wetsuit remains the call.
