Conditions at Avalanche in August
August: Late-Winter Grind
August keeps the winter theme alive with another 7.9ft (2.4m) average swell height and a 12.2s period. Swell energy is split almost evenly between SSW at 20.5% and SW at 21.2%, with S adding 9.7%, so most of the ocean is dominated by southwest quadrant groundswell. The wind is still the challenge: WSW is the leading direction at 18.8%, W contributes 13.5%, and ENE adds a sneaky 8.6% cross-onshore component. Ideal wind improves marginally to 21 percent. Water temperature bottoms out at 17.4°C and air averages just 16.1°C, so it is cold and raw. For the patient surfer, the best windows are the high pressure wedges between cold fronts, when offshore SW flow cleans up a solid SW/SSW groundswell and the NNE-facing beach gets a rare chance to show its shape.
