Conditions at Avalon in March
March: Transition Time - Periods Lift and Windows Open
March is the first real transition month. The average wave period climbs to 9.0s, and the ideal wind percentage jumps to 27 percent. Swell direction tilts even more into the favorable envelope: E 21%, ESE 21%, SE 20% and SSE 19%, while the less favorable ENE has faded to 10%. There is also a growing S component from early autumn fronts, which can wrap into Avalon but often needs lower tides. March's average height holds at 1.4m (4.6ft), with a healthy spread of 1.5-2.5m (5-8ft) waves in the SE/SSE bins during more active periods. The NE sea breeze is still common, so late afternoons remain wind-affected, but mornings are more consistently clean than in January or February. Water stays warm at 22.6°C, air temp drops to 21.0°C, and rainfall is lower at 3.33 mm/day. It's an excellent month for longboarding on clean autumn mornings and for the first proper SE swell of the season.
