Conditions at Two Ways in September
September: Monsoon Hairpins
September is the beginning of the end of the southwest monsoon. The average swell height eases slightly to 1.6m (5ft), the period remains strong at 10.5s, and the SSE sector still tallies 61.3% of the wave energy with S adding another 23.2%. The 1.5-2m band is still well represented, especially from SSE, so there is no shortage of size. What changes is the wind texture: ideal time improves to 31%, and although WSW and W still dominate, there are more frequent WNW and NW interludes as the synoptic pattern begins to oscillate. These windows offer the first decent chances for clean, semi-consistent surf in months. Air temperature is 27.5°C, water temperature is 29.3°C, and precipitation averages 6.03mm/day. If the monsoon starts to pulse, September can throw out a surprisingly good day or two.
