Conditions at Shivas in August
August: Monsoon Retreat Begins, W/WSW Swell Still Dominates
August is still in the monsoon trough, but the peak is easing. Average swell height eases to 2.1m (7ft), and the period drops a notch to 9.9s, giving the surf a more powerful, mid-period character rather than pure long-period groundswell. The wave rose is almost entirely favorable in direction - WSW (41.5%) and W (40.8%) combine for over 82% of the energy - with the majority in the 1.5-2m (5-6.5ft) and 2-2.5m (6.5-8ft) classes. However, clean windows remain rare: ideal wind is 8%, and the wind rose is still full of W (28.3%), WNW (27.9%) and WSW (17.6%) flow. Rainfall is still heavy at 23.22 mm/day, air temperature averages 26.1°C, and water has cooled to 27.5°C. August is a tease - big, powerful WSW swell is everywhere, but the onshore wind rarely gives Shivas a chance to show its shape.
