Conditions at Mossel Bay in March
March: Autumn Pulses with Extra Period
March keeps the summer consistency while adding a touch more groundswell. The average swell remains 6.6ft (2.0m), but the period lengthens to 11.2s, a sign that the Southern Ocean is waking up. SSW is still the big player at 30 percent, with S at 20 percent and SW at 8 percent. The north-northwest swell window is still quiet, but the S/SW wrap is more than enough to keep the bay solid.
Ideal wind is available 47 percent of the time, so the surf windows remain reliable. Air temperatures cool slightly to 20.7°C, water temperature drops to 20.3°C, and rainfall creeps up slightly to 1.43mm/day. The combination of longer swell periods and warm offshore mornings makes March one of the best months for both size and shape.
