March: The Great Transition - Cleaner Winds, Fading Direction
March is a true transition month. The average swell height drops slightly to 2.6ft (0.8m), but the period jumps to 10.6s, giving whatever does arrive a more powerful, lined-up feel. Swell from S (27%) and SSE (25%) now dominates, while the favorable E/ENE window has shrunk to around 19%. This is the classic issue at Alwars: the arrival of longer-period energy from the south is not from an ideal direction for an ENE-facing beach, so much of that 10-11s energy is likely shadowed or refracted into weakness.
The wind story is much better. Offshore flow from SSW, SW, WSW and W now totals around 31%, and the ideal-surf window jumps to 31% - a huge improvement over winter. This sets up a trade-off: cleaner, more groomed conditions but less optimally-directed swell. When the synoptic pattern allows a late-season NE/ENE pulse to run under offshore winds, March can produce surprisingly fun, glassy waves. Air temps average 28.8°C, water is 29.6°C, and rainfall is still modest at 0.98 mm/day.
