Conditions at Shivas in September
September: Monsoon Ebb, Better Angles and Fading Wind
September is where Shivas starts to wake up from the monsoon slumber. Average swell height settles to 1.4m (4-5ft) and the period stays at 9.8s, while the wave rose is dominated by optimal WSW energy (52.0%) with strong SW (22.5%) and W (17.3%) contributions - altogether, SSW/SW/WSW/W account for roughly 96.5% of the swell from the favorable western quadrant. Wave heights are mostly in the 1-1.5m (3-5ft) and 1.5-2m (5-6.5ft) categories, offering some legitimate ramps. The wind regime is improving too: ideal surfing time jumps to 22%, and although W/WNW/NW flow still occupies a large share of the wind rose, the monsoon is losing its grip. Rainfall drops to 11.45 mm/day, air temperature is 26.2°C, and water temperature is 27.6°C. September can deliver surprisingly good sessions, especially before the afternoon sea breeze kicks in.
