Conditions at Devil's Rock in August
August: Still Waiting for Autumn
August brings more of the same low-season pattern. The average swell holds at 5-6ft (1.6m), period ticks up slightly to 8.2s, and the swell direction remains almost locked in from the NNW at 93.8%. There is a little more NW swell (3.2%) than July, but not enough to change the character of the surf. Ideal wind rises to 35%, with light N/NE/ENE winds adding a touch more opportunity for morning glass. Water temperature is 18.1°C, air temps peak around 29.1°C, and rain stays minimal at 0.11 mm/day. It's a classic summer pattern: small, wind-affected NNW swell, clean enough for floating around but rarely firing.
