Conditions at Periscopes in September
September: Power Remains as the Season Turns
September is the last full month of peak season, and a very good one. Ideal wind is still at 81%, although the flow becomes more S (24.3%) and SSE (28.8%) and less consistently easterly; these southerly winds are less favorable than the dead offshore E/ESE flow but often remain clean until the sea breeze kicks in. Swell is still firing: average height is 1.7m (5-6ft) with a 14.3s period, and SSW swells provide 76.8% of the energy, with SW adding 16.8%. The 1.5-2m (5-6ft) class holds 45% of the waves and almost 17% is in the 2-2.5m (7-8ft) range. Rain stays low at 0.52mm/day, air temp is 26.3°C and water temp is 26.8°C. Expect plenty of powerful surf with the first slight inconsistencies of the transition creeping in.
