Conditions at Cables in March
March: Autumn Swing - Longer Periods and Cleaner Wind
March marks the first real shift of the surf year. The swell height holds around 1.8m (6ft), but the average period lengthens to 12.4s as the first strong frontal systems of autumn spin up in the Southern Ocean. SW swell dominates with 50.3% of the distribution, SSW adds 27.7%, and WSW nudges up to 3.9%. The extra period and slightly more westerly angle in the swell are the first signs that the low season is ending.
Ideal offshore wind ticks up to 35% in March. The wind rose is better balanced, with ESE (13.5%), E (12.8%) and SE (9.2%) all contributing, while SSW drops to 15.4%. Rain remains light at 0.66mm/day, water is still warm at 22.2°C and air temperatures average 22.4°C. This is a transition month: the surf is not yet at winter size, but the windows are longer and the ocean is starting to organize.
