Conditions at Long Beach in March
March: The Autumn Transition Begins
As the austral autumn sets in, the average wave period climbs to 11.7s and the surf becomes slightly more organised. Ideal wind time improves to 17 percent as the SE/SSE trades ease somewhat, with SE at 27.7 percent and SSE at 21.3 percent, while the onshore NNW wind starts to appear at 6.6 percent. Swell size averages a solid 7.5ft (2.3m), with SW at 25.7 percent and SSW at 21.0 percent making up most of the spectrum. The heavier size bands are now better represented, and over 8ft (2.5m) swells start to creep in from the SW and SSW. This is a good month for long-period, powerful lines at Long Beach, especially when a low-pressure system passes south of the continent and the wind turns offshore. Water temperature cools to 17.7C, air temps remain mild at 19.4C, and precipitation begins to edge upward.
