Conditions at Kate's in September
September: Late-Season Quality Holds
September keeps the Southwest Monsoon energy spinning. SSE is again the leading swell direction at 35.4%, with S at 21.4%, and the average period stubbornly holds at 9.0s. Ideal wind remains high at 51%, driven by W (31.6%) and WNW (25.5%). This is a slightly more mixed spectrum than August-SSW (13.5%), SW (10.1%) and WSW (8.5%) add some angled energy-but there are plenty of quality SSE pulses to keep Kate's firing. Average heights are 1.2m (4ft), and when the W wind is blowing, the reef holds a nice, hollow line. The water is still a warm 28.9°C, air 27.5°C, and rainfall is high at 6.08mm/day; be ready for tropical thunderstorms.
