Conditions at Ervik in August
August: Warm Water, Autumn Rumblings
August remains small, but the tide begins to turn. Average swell height moves back up to 3ft (0.9m), period to 7.6s, and while the swell rose still peaks in the 0.5-1m range, there is a more consistent thread of 3-5ft (1-1.5m) energy from the NW quadrant. NNW at 17.3%, WNW at 10.1% and NW at 9.4% keep the optimal swell directions alive, while SSW at 10.6% and WSW at 11.7% hint at the first autumn low-pressure pulses.
Wind is actually more offshore-friendly in a statistical sense: the S/SSW/SW/WSW quadrant totals nearly 40%, with SSW at 14.9% and SW at 11.1% leading. But the Atlantic is still asleep, so ideal surf windows are only 13%. Water temperature is the year's warmest at 15.1°C, air averages 13.9°C, and precipitation picks up slightly to 4.92mm/day. For anyone who loves warm-water storm-surf hunting, the late August, south-wind-before-a-low windows can already produce surprisingly crisp, hollow waves.
