Conditions at Amoreira in August
August: Late Summer Smallness and Occasional Pulses
August is very similar to July. Average surf remains 4-5ft (1.4m) and the period is 8.9 seconds. The swell direction is still locked into the NW quadrant, with NW at 59.0 percent, NNW at 29.7 percent and WNW at 8.9 percent, so Amoreira sees plenty of short-period northwest windswell. There can be occasional better pulses when a low-pressure system drifts into the eastern Atlantic, but long-period groundswell is rare. Ideal wind windows improve only slightly to 9 percent, and the story remains the same: NNW winds dominate at 54.4 percent and NW at 16.2 percent. Light mornings are the only real chance for smooth, groomed waves. Water temperature is the warmest of the year at 17.9°C, air averages 23.1°C, and rain is very scarce. A summer board and patience are required, though the consistency is actually decent for small-wave training.
