Conditions at Sagres in March
March: The Last Consistent Winter Pulse
March keeps Sagres in solid surf. Average swell is 7ft (2.2m) with a 12.3s period, and ideal wind is 25%. The distribution still leans heavily on the NW quadrant-NW 27.6%, WNW 17.4%, NNW 12.6%-with 6.3% W. Favorable SE/SSE/S/SSW swell is still uncommon at roughly 1.6%, so it is again all about NW groundswell bending around the cape into the SSE-facing beaches.
NNW wind dominates at 28.4%, followed by NW 7.8%, N 7.0%, and ESE 7.4%. Onshore S/SW flow remains modest, but easterly winds can introduce texture. Water temperature holds at 15.6°C, air averages 14.8°C (7.0-22.8°C), with 2.00mm/day of rain. This is a great month for a thick suit and a high-performance shortboard; plenty of long-period swell is still marching through the eastern Atlantic.
