Conditions at Sandvik in August

August: Last of the Summer Lull

August is the final month of the summer lull, with average swell height still stuck around 3-4ft (1.1m) and a short 8.4s period. SW (25.5%) and SSW (16.4%) dominate the swell rose, but again most energy is in the 0.5-1.5m window. The water temperature peaks for the year at 11.8°C, while air temperatures average 10.5°C and precipitation starts creeping back up to 3.67mm/day. Ideal offshore winds occur around 17% of the time, but the wind rose remains split between N/NNW flow and ESE/SE flow. The first hints of autumn are in the air, and if an early-season low-pressure system forms, it can deliver the first waist-to-chest-high swell of the approaching season-a teaser of the winter to come.
