Conditions at Dee Why Point in March
March: The Autumn Transition Begins
March is the first month that Dee Why Point starts to shake off the summer grind. Swell height remains a solid 5ft (1.7m), but the average wave period climbs to 9.2s, giving the surf more shape and push. The E and ESE directions still combine for about a third of the total swell, while SE and SSE energy begins to take over as the autumn storm track becomes more active. The wind field changes too: the offshore SW, WSW and W components strengthen, pushing the ideal wind percentage to 22% and creating more frequent clean windows.
Air temperatures ease to 21.6°C, water sits at 23.1°C and rainfall drops to 3.13 mm/day. This is a month of hope at Dee Why Point, with punchy, rideable surf and a growing number of morning glass-off sessions as the East Coast transitions toward winter.
