Conditions at Killer Point in March
March: Winter Swell Holding Strong
March is the last full month of true winter power at Killer Point. Average swell height remains at 2.2m (7.2ft) while the period eases only slightly to 12.4s. The direction mix is still dominated by NNW 35.0% and NW 27.3%, with WNW adding 9.4%. This creates a very workable west/northwest window, though the NNW component is edging higher as the season progresses. Most waves fall in the 1.5-2m and 2-2.5m bands, so expect punchy, powerful surf with the occasional overhead-plus standout set.
Wind quality starts to fade a little: the ideal offshore percentage drops to 40%. The northerly trades are strengthening, with NNW 26.2% and NW 12.5%, but ENE through ESE offshore flow still appears often enough to keep the lineup clean on the better days. Water temperature sits at 17.0°C, air at 17.5°C and rain is still possible at 0.80mm/day. March can be a sneaky good month; the tropical air is warmer and the big winter groundswells haven't completely shut off.
