Conditions at Supersuck in September
September: Clean Strength
September keeps the big SSW groundswell train rolling - average 1.6m (5-6ft), period 14.2s, with an incredible 86.3% of all waves arriving from SSW. The 1.5-2m range accounts for 39.5%, and 10.9% reaches 2-2.5m, so there is still serious size in the water. What changes is the wind: the trades ease just enough to lift ideal surfing wind to 70%. SE (46.1%) and SSE (24.0%) are the main offshore flows, with fewer mega-gusty episodes than July and August. Rain remains minimal at 0.93mm/day, water is 28.0°C and air is 25.7°C.
September is often the best balance of size and cleanliness at Supersuck - long-period, powerful SSW groundswell groomed by consistent trade-wind offshore flow.
