Conditions at Caldera in August
August: Peak Rain, Same Tiny Swell
August is meteorologically active, with precipitation averaging 5.29mm/day and the ITCZ overhead bringing unstable skies and variable winds. The swell story remains stubbornly small: average height is about 1ft (0.3m) and the average period is 14.1s. Directionally, SSW is still dominant at 73.5%, with SW at 10.2% and S at 14.0%. The wind field is split between offshore NNE/NE/ENE/E flow at around 23% and onshore S/SSW/SW flow at around 38%, so conditions often come down to a clean early window versus afternoon onshore mush. Water temperature is warm at 29.5°C. If you are chasing the rare 2-3ft (0.5-1m) SSW pulse, dawn patrol and a decent tide will be your best allies, but be prepared for plenty of flat, bumpy hours.
