Conditions at Praia da Cal in March
March: Transitional Shift Begins
March is the hinge month between summer and autumn. The average wave height inches up to 5ft (1.5m) and the period stretches to 8.8s, so there's a bit more push behind the trade swell. Swell directions swing further southeast - ESE (22.3%), E (20.7%), SE (18.5%) and SSE (15.3%) combine for a healthy 76.8% of all wave energy, with S (8.6%) also starting to show. This is a cleaner directional setup for Praia da Cal. Ideal wind reaches 39%, with the offshore quadrant (W, WNW, NW, NNW) accounting for about 15% of the time, while the NE trade (15%) weakens slightly. Water is still warm at 23.7°C, air drops to 21.7°C, and precipitation eases to 3.95 mm/day. Expect fun, rippable surf with increasingly reliable windows as autumn takes hold.
