Conditions at Sao Lourenco in May
May: The Shoulder Season Fades
May is when summer takes control. Average swell height drops to 1.7m (5.6ft) and the average period shortens to 9.9s, indicating a shift toward shorter-period NW and NNW windswell. The swell rose is heavily weighted to the NNW (31.5 percent) and NW (30.5 percent), but much of that energy is below the threshold for quality surf at Sao Lourenco.
Wind is the spoiler: NNW winds blow 36.5 percent of the time and ideal offshore wind plummets to just 9 percent. Most days are small, short-period and wind-affected. The saving grace is the warmer weather - air average 16.7°C and water 16.5°C - making a groveling longboard session more appealing than a serious search for barrels.
