Conditions at Praia da Rocha in March
March: Spring Breeze, Winter Swell
March is a transition month, but the transition is slow. Average swell height is still solid at 4.3ft (1.3m), and average period remains in the powerful class at 12.1s. The swell distribution is less southwesterly than January and February, with WNW (28.5%) and NW (26.6%) dominating and W increasing to 14%, which actually favors the beach slightly better than pure NW. S-SSW-SW-WSW totals near 10%, meaning there are still plenty of windows for proper surf. Ideal wind drops to 34% as the landmass heats up and afternoon seabreezes become more frequent, but morning N-NNE offshore flows still hold the surf together. Air temperature climbs to 14.8°C, water temperature is 15.6°C, and rainfall is 2.00mm/day. Expect occasional punchy windswell mixed with clean long-period groundswell.
