Conditions at Altura in August
August: The Flattest Month of the Year
August is the true flat spell at Altura. Average swell bottoms out at around 1-2ft (0.4m) and mean period is 4.7s, with most energy arriving as short-period windswell. SE still appears at 13.8 percent, and combined southern quadrant swell is about a quarter of the total, but the size is tiny and the period is too short for the wave to find any shape on the beach. WSW and W account for nearly 40 percent of the background swell and are of little use to this SSE-facing stretch. The wind is still overwhelmingly offshore in direction, with NNW at 35.2 percent and NW at 11.3 percent, yet ideal surfing wind falls to 14 percent because there is no swell to push things cleanly. Water temperature peaks at 21.7C and air at 24.1C, while rain averages just 0.09 mm/day. If a tropical or southern-hemisphere swell lines up, it can save the month, but otherwise August is a rest month.
