Conditions at Scar Reef in September
September: Late Dry Season Fire
September keeps the dry-season momentum going, though there are subtle signs of change. Ideal wind is still 87 percent, precipitation creeps up to just 0.93mm/day, and the average swell remains 5ft (1.6m) with a 14.2s period. Wind direction shifts a little more southerly - S at 39.0%, SSE at 42.8% - which is still offshore enough to keep Scar Reef clean. Swell is incredibly one-directional: SSW contributes 86.3% of all readings, with 39.5% in the pumping 5-6.5ft (1.5-2m) range and 10.9% pushing into 6-8ft (2-2.5m) groundswell. Water temp warms to 28.0°C and air hits 25.7°C. This is still a high-quality month, and one of the best bets for solid, lined-up surf before the monsoon shift.
