Conditions at Warner Beach in September
September: The Spring Fade Begins
September is a shoulder month with a foot in both seasons. The average wave period drops back to 9.6s, and ideal wind falls to 38%, while the average surf height remains 6ft (1.8m). The swell direction is still very good: S 19%, SSE 17%, SE 15%, ENE 14%, E 13% and ESE 13%. The strength is still there, especially from S and SSE, but the wave period is no longer in the 10s-plus range of winter, so the larger surfaces lose some of their structure.
Spring is arriving in the wind field. NE/ENE flow rebuilds to nearly 21%, and the SSW/S/SW winds also increase, creating more variable and often cross-shore conditions. True offshore windows are now limited to about 15% of the month. Rainfall climbs to 2.79mm/day, water temperature is 21.3°C, and air temps rise to 17.1°C. It is still worth paddling out, especially in the lulls between frontal passages, but the quality is no longer a slam dunk.
