Conditions at Santo Amaro in August
August: Wait for the South Swell Window
August sits in a similar summer groove with 4ft (1.3m) average swell and a slightly longer 8.9-second period. The NW direction remains the dominant swell source at 44.4 percent, and NNW adds another 40.1 percent; essentially all the energy arrives from the north-west quadrant. Wind ideal frequency climbs to 47 percent as the trade-like NNW flow (61.6 percent) begins to relent slightly compared to July. Water temperature peaks at 18.0°C, with air temps at 20.5°C and very little rain (0.18 mm/day). Although this is a low-energy month, occasional pulses of S or SW groundswell-often from ex-hurricanes spinning up the Atlantic-can light up the beach with unexpected quality. When that occurs with an offshore N morning wind, August can surprise you.
