March: First Real Pull of Autumn
Autumn arrives and the storm track begins to wake up. Average swell height inches up to 8ft (2.4m), the wave period stretches to 12.4s, and the direction stays locked in the SW/SSW/WSW envelope. SW still dominates at 34.9%, with SSW at 12.7%, while WSW adds 7.4%. The mid-size 1.5-2.5m (5-8ft) range holds the bulk of the energy, but there are also slightly more XXL pulses above 2.5m (8ft) as the first big frontal systems get organised.
The ideal wind percentage climbs to 28%, the highest since summer began, as the subtropical ridge starts to drift north and pre-frontal N/NNE flow becomes more common. The offshore quadrant now takes up about 14% of the wind rose, and the S-SW onshore dial backs a touch. Water temp remains a comfortable 18.0°C, average air temp is 16.7°C, and rain is still only 1.70 mm/day. March is the perfect transition month: enough warmth, enough size, and the first genuine taste of reliable clean swell.
