Conditions at Bombies in September
September: The Fading Trade Monsoon
September remains locked in the southeast monsoon, with SE winds at 66.1% and SSE at 18.5%. Ideal wind is at a yearly low of 2% -- essentially a no-go for clean conditions unless a strong anomaly breaks the pattern. The swell stats are still excellent: average 2.0m (6-7ft), period 14.1s, S swell now dominant at 55.7%, with SSW at 24.0% and SSE at 8.2%. The direction of the swell is almost perfectly perpendicular to the beach, so energy is maxed at the reef. The problem is not size, it is surface texture. If a rare NW wind event pushes the trades away, this will be one of the heaviest and most consequential sessions of the year. Air 26.9°C, water 28.4°C, rain 2.7mm/day.
