Conditions at Praia da Rocha in July
July: Peak Summer Lull - Small, Clean and Groveling
July is the most extreme low point of the year. The average swell height is just 2.6ft (0.8m) and the average period bottoms out at 8.0s, the lowest of any month. A massive 61.5% of all wave energy arrives from the NW, with another 20.5% from WNW, almost all of it in the 1.5-3ft (0.5-1m) range. The direct S/SW/WSW window is less than 1%, so true Praia da Rocha surf is rare. Ideal offshore wind is 27%, and the wind rose is dominated by NNW (36.8%) and NW (23.9%), meaning the combination of short swell and cross-shore wind makes conditions marginal. Air temperature is 21.3°C, water temperature 19.1°C, and rain is almost zero at 0.04mm/day. Summer fun on the beach is maximum; surf is minimal.
