Conditions at Manly in March
March: Autumn Energy Arrives
March is a transition month, but it still delivers. The average swell holds at 5-6ft (1.7m), the period lengthens to 9.2s, and ideal offshore flow remains healthy at 45%. SSE swell becomes the dominant direction at 19.3%, with S and SE energy also on the rise - an early taste of Southern Ocean groundswell filtering into the region. For Manly, this is a step closer to the S/SE window that can wrap into a west-facing beach, though true W/SW swells remain rare. Combined with a mixed wind regime of NE, S and SSE, conditions become a chess game; when the offshore E/NE flow aligns, the waves are punchy and rippable. Water temperature cools slightly to 23°C and autumn air temperatures of 21-22°C make for excellent sessions.
