Conditions at Il Castello in August
August: Flat and Onshore
August repeats July's pattern with the lowest ideal wind of the year at just 8%. Average swell remains 0.5m (1.6ft) and the period is 4.0s. The WSW swell window is still the leader at 20.5%, but the distribution is even more bottom-heavy: around 10.5% of all observations are below 0.5m. Onshore flow is relentless - W wind accounts for 10.2%, WSW for 8.7% and SSE for 7.0% - so the beach is often riddled with chop. The warm water at 25.1°C (77.2°F), air temperatures averaging 25.1°C and minimal rainfall (0.8mm/day) make it a gorgeous beach day, but not a surf day. For surfers, this is a month to worship the small-wave board and the dawn patrol, or to go chase the rare larger swell that sneaks into the western Med.
