March: Autumn's First Long-Period Pulse
The Southern Ocean storm track begins to wake up in March, and Shark Rock Pier feels it. Average swell height is 6.5ft (2.0m) with the period ticking up to 11.4s. SSW swell is again the leader at 27.9%, with S at 20.2% and SW at 8.3%; SSE also adds 11.4%. The 5-8ft (1.5-2.5m) range is the dominant wave-height class, so there is plenty of power to keep the pier alive.
The ideal wind percentage is still high at 28%, and offshore S/SSW/SW/WSW flow totals roughly 37%. Air temperatures cool slightly to 21.4°C, water temp backs to 19.7°C, and rainfall edges up to 1.59 mm/day. This transition month offers the best of both worlds: summer's lighter winds with the first solid taste of autumn groundswell. If a cold front sweeps through and the winds clock from NE to SW, clear your schedule.
