Conditions at Cave in August
August: Late-Summer Light and Slightly Better Offshore Odds
August remains small at Cave, with average swell height holding at 4.6ft (1.4m), but the average period ticks up slightly to 8.9s. The energy field is still dominated by NNW swell at 50.7% and NW swell at 35.1%, leaving the southwest-facing spot with only infrequent direct W/WSW groundswell. The one piece of good news is the wind: ideal E/NE offshore flow increases to 19%, the best of the summer months, and the frequency of strong NNW wind drops slightly. Air temperatures reach their annual peak of 20.7°C, water temperature is 17.8°C and rainfall is minimal at 0.25mm/day. August is mostly a small-wave month, but the occasional late-summer Atlantic pulse can provide clean, playful peaks for riders on mid-lengths and fishes.
