Most waves are still in the 2-5ft (0.5-1.5m) range, though a few larger pulses appear toward the end of the month as the Atlantic begins to wake up. Ideal wind improves slightly to 31 percent, but onshore NNW flow still dominates 19 percent of the time. Sea surface temperature peaks at 21.7°C, air averages 20.9°C, and precipitation is 1.52 mm/day. August is warm, crowded, and small, but the first hints of autumn are not far away.
