Conditions at Praia da Barra in August
August: Still Sleeping, But the Pulse Stirs Late
August remains deep in the low season, but the first faint signals of autumn start to appear by the end of the month. Average swell height is 4-5ft (1.4m), period 9.0s, and ideal wind 15 percent. The dominant NW swell direction accounts for 46 percent, with NNW another 32 percent and WNW 16 percent. Most waves are small, grovelly and short-period, but distant storms begin to push occasional overhead pulses late in the month. The daily NNW wind still blows 49 percent of the time, making conditions tough until an E/ENE offshore flow sets in overnight. Water temperature is the warmest of the year at 17.9°C and rain is scarce. Keep the log handy, but watch the forecast for an early autumn pulse.
