Conditions at Jardins do Mar in August
August: Cleaner Winds, Still Small
August remains small but the wind stats improve noticeably. Average swell holds at 4.6ft (1.4m), with the average period creeping back to 9.1s. The swell mix is still locked in the northern hemisphere summer pattern: NNE (33.0%), NNW (33.5%), N (18.0%), and NW (8.2%), while ideal W/SW/SSW swells are almost non-existent. However, the ideal offshore wind window jumps to 56%, the highest of the year, as the trade flow becomes more moderate (NNE 38.1%, NE 29.5%). This creates more glassy mornings even on the small waves. Water temperature reaches 23.2°C, air temps reach 22.9°C (min 20.5°C, max 26.7°C), and precipitation stays very low at 0.23 mm/day. Perfect for summer cruises and longboard carves, but if you want real power, you'll need to wait for autumn.
