Conditions at Caswell Beach in August
August: Still Small, But the Ocean Begins to Stir
August remains in the summer lull, but there are subtle signs of life. The average swell height holds at 2-3ft (0.8m) with an average period of 7.4s; however, the west-dominated energy starts to show a slightly bigger distribution above 1m, and occasional pulses from the SW can put a bit more shape into Caswell. WSW/W still accounts for around 72% of all swell, while the preferred SSE-S-SW sector sits near 11%. Ideal offshore winds remain scarce at 12%, and warm sea breezes often kick up by midday. With air temperatures at 16.3°C and water at a summer-maximum 18.0°C, August offers the warmest surf of the year. It is not big, but for small-wave practice and long summer sessions it can be rewarding.
