March: Autumn Transition with Added Southwest Punch
March begins the autumn transition. The average swell remains 8ft (2.5m) at 11.4 seconds, and the ideal wind window still comes in at 30 percent. SSW and SW remain dominant, with 18.3 and 10.8 percent respectively, while S now delivers 11.8 percent as the storm track starts to nudge north. E-angled swell drops fractionally to 1.8 percent. Onshore ENE and E flow still appears around one-third of the time, but W and WSW add a combined 32.3 percent, and lighter S/SSW winds open up more offshore options. Water cools to 19.0°C, air averages 20.7°C, and rain picks up to 1.76 mm/day. March can deliver excellent late-autumn surf when a reinforcing southwesterly wind follows a cold front and the swell direction bends more easterly.
