Conditions at North Stradbroke Island in March
March: Solid Swell, Still Trading Onshore
March sees the autumn equinox approach, but summer's wind regime has not got the memo. The average swell holds at 1.3m (4ft) and the period stretches to 9.0s, giving the waves a bit more push. ESE swell jumps to 33%, E to 32%, and SE to 16% - ideal directions for the beach, but again the trade winds rule. SE winds blow a full quarter of the time (25%), with ESE at 19% and SSE at 15%, so the onshore component is massive. Ideal offshore flow remains at just 12%. When a westerly does show up, usually in the wake of a weak cold front, the surf can turn on quickly, but those windows are still limited. Water temp is 26.4°C, air temps average 24.8°C, and rainfall is 4.60mm/day.
