Conditions at Newport Beach in August
August: The Warmest Water and the Same Summer Rut
August is very similar to July, with an average swell height of 0.8m (2-3ft) and a long 13.7s period. Swell is dominated by SW at 45.3%, SSW at 27.2% and WSW at 23.0%. There is a slight increase in S-direction energy compared with June, but the overall height distribution remains small, with most swell sitting in the 0.5-1m (2-3ft) category.
Onshore winds are the defining factor. Ideal offshore flow is just 2%, with W at 34.6% and WSW at 24.1% ruling the afternoons. Water temperature peaks at 18.0C, air temperature reaches 20.9C, and rain is essentially absent at 0.03 mm/day. The warm water and consistent south-southwest swell can tempt you out, but be prepared for wind-affected surface conditions and long lulls between the better sets.
