March: The South Swell Engine Fires Up
March marks the real transition into peak season. Average wave heights are around 5ft (1.5m), while the period climbs to 12.9s, firmly in the powerful long-period category. The directional distribution flips heavily toward the optimal quadrant: SSW leads at 43.1%, SW adds 16.2%, S adds 13.8%, and the whole SSE-SW window totals more than 75%. The most common class is 1-1.5m (3-5ft), but SSW and SW also show a notable 1.5-2m (5-6.5ft) component.
The limiting factor is wind - ideal conditions drop to 47%, with W, WSW and SW breezes becoming more frequent in the afternoons. Air temperatures rise to 28.2°C and water temperature 27.8°C, while rainfall remains minimal. Early mornings are the key: get out before the thermal sea breeze builds and you'll be rewarded with clean, lined-up, long-period SSW swell.
