Conditions at Assinie in August
August: Monsoon Max with Maximum Swell
August is statistically the worst month for Assinie's surf quality, with ideal offshore wind registering 0% of the time. Average swell height stays at around 4ft (1.3m) and the period peaks at 11.7s, with S energy at 64.8% and SSW at 35.2%. The height distribution shows 52.5% from S in the 3-5ft (1-1.5m) range, 7.2% from S at 5-6.5ft (1.5-2m) and a sliver of 6.5-8ft (2-2.5m) from SSW. There is no shortage of power.
But the wind rose is dominated by southwest winds: SW 51.9%, WSW 16.3% and SSW 25.6%. A full 33.3% of observations are SW at 10-20kph, with even a tiny piece of 20-30kph. Water temperature reaches its yearly minimum of 23.9°C, air temperature drops to 24.3°C and rain is low at 1.43mm/day. The upwelling-driven onshore flow and big S/SSW groundswell create heavy, messy, stormy surf. It is still special for those who appreciate raw African power, but rarely the clean, rippable waves most surfers are after.
