Conditions at Sao Lourenco in July

July: Peak Summer Snooze

July is the deadest month of the year for surf quality. Average swell height bottoms out at 1.4m (4.6ft) and average period at 8.5s. The waverose is dominated by NNW swells at 54.2 percent, with NW contributing 33.0 percent. This is the classic Portuguese summer pattern: small, weak, short-period NW windswell washing onto the west-north-west facing beach.

Winds are even more one-dimensional, with NNW at 59.4 percent and ideal offshore wind at a paltry 3 percent. Expect mostly marginal, wind-blown conditions. On the rare day when the northerly eases and an easterly offshore breeze appears, even the small 1-1.5m (3.3-4.9ft) peaks can be fun on a log. Water is 17.4°C and air averages 20.2°C.
