Conditions at Meia Praia in August
August: Tiny Swell, Warm Water and the Promise of Autumn
August is statistically the smallest month of the year, with an average swell height of just 2ft (0.6m) and a period of 8.6s. NW (59%) and WNW (24%) continue to dominate the swell window, while the favourable south/southwest swells are almost absent. The average period ticks up slightly from July, and ideal wind improves to 27%, so the small surf becomes a bit more organized than midsummer.
NNW (47%) and NW (25%) winds still blow offshore, keeping the lineups clean but small. Water temperature is at its warmest at 19.6°C, air averages 21.8°C, and precipitation is only 0.10mm/day. This is still longboard territory - waves are generally in the 1-3ft (0.3-0.9m) range, with the rare late-August swell hinting that the Atlantic is beginning to stir.
