Conditions at Refsnes in August
August: Last Days of Summer
August brings the first subtle signs of autumn, but it is still a summer lull overall. Average swell height creeps up to 4ft (1.2m) and the average period stays short at 6.6s. Swell from the ideal W/SW direction is actually well represented - over 36 percent of observations - but the period rarely stretches enough to give the waves real power. The northwestern quadrant still dominates the background, and this mix creates a messy, shifting lineup more often than a clean, grinding break.
Ideal offshore wind conditions appear only 14 percent of the time; NNW and NW winds remain relentless in the data. Still, August has the warmest water month of the year at 16.7°C, air temperatures average 15.0°C and precipitation is modest compared with winter. It may be the best month for beachgoers, but surfers are waiting for the first real W/SW groundswell of the new season, which often arrives as a promising pulse right at the end of the month.
