Conditions at Cap Gris-Nez in August
August: Warm Water, Weakest Period
August shows a tiny bounce in wave height to 2ft (0.6m) but the lowest average period of the year at 4.7s. The north window is still present at 32%, with NE 12.4% and NNE 10.4%, but the height distribution is stuck in the 0-2ft (0-0.5m) and 2-3ft (0.5-1m) bins. WSW wind dominates at 23.9%, SW contributes 15.7%, and ideal surf frequency creeps back to 6%. Sea water temperature peaks at 18.9°C - the warmest water of the year - and air averages 17.6°C, with moderate rain at 2.02mm/day. For most surfers August is an acceptable washout: the rare NNE swell with a SSW offshore can create two-foot beach peaks, but the background state is micro-swell and choppy texture. Bring a longboard, keep expectations low, and enjoy the warmest air of the year.
