Conditions at Ansteys in March
March: Autumn Edges Into the Forecast
Autumn arrives slowly but noticeably. The average swell height is still 5-6ft (1.7m) and the average period reaches 9.8s, so there is more power in the water than in the summer months. The swell window is still excellent: E/ESE/SE/SSE sources supply roughly 79% of the energy, with ESE (21.6%) and SE (20.7%) leading the way. It is a season of 3-6ft (1-2m) waves, but the 6-8ft (2-2.5m) class is scattered through the S and SE directions, a sign of early Southern Ocean groundswell starting to arrive.
Wind becomes slightly more favorable. NE and NNE still combine for nearly 38%, but SSW also sits at 17%, and the ideal wind percentage jumps to 28%. The onshore E/ESE/SE/SSE flow drops to around 13%. With water temperature at 25.6°C and air at 24.7°C, you are still wearing summer boardshorts, but the lower rainfall (2.95mm/day) hints at drier synoptic patterns. Keep an eye on frontal activity to the south; a W/NW change is the golden ticket.
