Conditions at Guarita in March
March: The Autumn Transition Begins
March is a turning point at Guarita. Average swell builds slightly to 1.5m (5ft) and period lengthens to 8.8s, signaling the first real injections of longer-period energy from the southern oceans. The swell direction shifts a bit more toward the SE-SSE-S arc: ESE 22.3%, E 20.7%, SE 18.5%, SSE 15.3%, and S 8.6%, with SSW contribution climbing to 1.4%. This is a slow but noticeable decrease in pure east trade-swell dominance and an increase in south-sourced groundswell. On the wind side, NE still leads at 15%, but offshore NW/NNW flow is more frequent than earlier in summer; ideal wind sits at 41%. The surf is more consistent now, with a mix of trade windswell and building S/SSW pulses. Air temperatures cool to 21.7°C, water temperatures hold at 23.7°C, and rain eases to 3.95mm/day.
