August: The Cleanest Window of the Year
August is statistically the best month for surf quality at Big Rock. Ideal offshore winds peak at 78% - the highest of any month - with WSW, SW, SSW and W flow creating long stretches of clean surfaces. Swell heights average 1.0m (3.3ft) and periods reach 9.4s, the longest of the year. The wave rose remains dominated by SSE and S swells, so the direction is not perfect, but these swells are consistent and have enough period to wrap and stand up along this ENE-exposed stretch of coast. Expect a mix of 2-3ft (0.5-1m) and 3-5ft (1-1.5m) surf with the occasional 5-6ft (1.5-2m) pulse. Water temperature holds at 29.0°C, air temp at 29.0°C, and precipitation is higher at 4.22mm/day as the monsoon peaks. If you want the best chance of clean, warm-water waves, August is your month.
