Conditions at Santo Amaro in March
March: The Tail End of Winter Punch
March still carries serious winter muscle. Average swell height is 7ft (2.2m) with a 12.4-second period, and the NW direction is the clear workhorse, accounting for 27.8 percent of all swell observations. Adding WNW and NNW brings the north-west quadrant total near 59 percent. Wind conditions hold at 44 percent ideal, with NNW blowing 25.9 percent of the time and NW adding another 8 percent, creating plenty of clean, offshore-run days. As spring tries to push north, air temperatures warm to 14.0°C and water remains cool at 14.8°C. The storm track is still strong enough to send XL pulses, especially during negative NAO phases, but the average intensity is slowly backing off from the January peak. Expect powerful, grinding peaks with the occasional standout session when an ESE-to-S swell aligns with a light N wind.
