Conditions at Cronulla in March
March: Autumn Transition Begins
March is where Cronulla starts to shake off the summer monotony. The average swell height stays at 5-6ft (1.7m), but the average period lengthens to 9.2 seconds. East and ESE swells remain strong, yet SSE becomes the single largest directional source at over 19% of the wave distribution, signaling that Southern Ocean low-pressure systems are starting to fire. There is a distinct increase in 2-2.5m (6-8ft) SSE and S swells, adding power to the lineup.
Wind quality improves noticeably, with ideal offshore conditions up to 19% of the time. While NE sea breezes still dominate the afternoon, westerly and south-westerly winds are more common in the mornings and during frontal passages. This is a transition month: the right combo of a developing Tasman low and a west wind can deliver clean 5-6ft (1.7m) waves at Wanda and North Cronulla before the afternoon seabreeze. Water temp remains warm at 22.8°C and air temps average 21.6°C.
