Conditions at Cat Bay in March
March: Autumn Smoothness
March still sits solidly in the good surf zone. The average swell is 1.4m (4.6ft), the period extends to 12.0s, and offshore wind frequency remains high at 44%. SW swell is once again the engine room at 52.0%, while SSW adds 21.8% and WSW contributes 6.4%. This is a month where the longer period allows the SW groundswell to wrap more efficiently into the north-northwest-facing beach. The bulk of waves are in the rippable 3-5ft (0.9-1.5m) range, and almost a third of the total swell population exceeds 1.5m (5ft). Wind observations are still favourable, with SSW at 10.0%, SW at 11.4% and S at 8.6%, while NNW onshore flow is only 6.0%. With water temperature at 18.8°C and relatively low rainfall of 1.41 mm/day, March is a reliable pick.
