Conditions at Praia do CDS in August
August: Peak Summer, Small but Persistent
August is very similar to July. Average swell remains at 3ft (1.0m), period 9.1 seconds, and the NW direction continues to dominate with 66 percent of the swell, supported by 24 percent WNW. The consistency is actually quite good; it's just that most of the energy is small and short-period. Occasionally a passing tropical swell or an unusually strong Atlantic low can deliver a bigger 5-6.5ft (1.5-2m) day, but those are the exceptions in an otherwise mellow month.
The wind story is nearly identical to July: NNW at 62 percent and NW at 12 percent leave the lineup exposed to a persistent cross-shore flow. Ideal wind is 27 percent, and the best conditions are found in the early morning hours before the daily breeze builds. Water temp is at its annual peak of 18.0°C and air temp averages 20.5°C. Precipitation is minimal at 0.18mm/day, making it a gorgeous month to be at the beach - even if the surf is small.
