Conditions at Martinhal in August
August: Late Summer Windswell, Slightly Better
August begins to feel the first hints of autumn. Average swell remains around 4.5ft (1.4m), but the period ticks up to 8.7s, and the Atlantic occasionally sends a more organised pulse. NW at 47.2% and NNW at 41.4% dominate again, with WNW adding 6.9%. Wind is still largely strong from the NNW at 65.4%, though the heat low starts to loosen its grip and ideal conditions reach 26%. Water temp reaches 18.9°C, air averages 21.8°C with highs near 33.3°C, and rain is just 0.10mm/day. August is a summer-grovel month with fun, rippable small waves on the best days, especially when a late-season tropical system in the Atlantic adds a little more period and size.
