Conditions at Nazare in August
August: Late Summer Flickers
August is as slow as July at first glance, but the numbers show a slight uptick in clean windows. Average swell height still sits at 4ft (1.3m), and period has improved marginally to 9.0 seconds. The swell direction remains locked in the north: NW 50.8 percent, NNW 29.2 percent, WNW 16.1 percent, W 2.4 percent. Summer windswell is the theme, though the longer-period component can occasionally push through. Ideal offshore wind climbs to 31 percent, and although NNW still dominates at 61.6 percent, the sea breeze pattern and a few early-season pulses can make for fun dawn surfs. Water temperature reaches its warmest at 18.4°C and precipitation is minimal at 0.34 mm/day. Keep expectations low for size, but don't write off August completely; if a pulse lines up with an offshore morning, there can be fun waves.
