Conditions at Almagreira in March
March: Still Firing as the Season Turns
March is the last true winter month at Almagreira. The ocean is still generous with 8ft-plus (2.5m) average swell and a 12.4s period, and the swell distribution is even more concentrated in the optimal quadrant: WNW, NW and NNW combine for over 51% of all readings. The northwest Atlantic is still producing strong extratropical storms, so long-period swell lines still hit with authority, often in the 5-8ft (1.5-2.5m) range.
Wind is the limiting factor as the month progresses. NNW wind skyrockets to 20.8% frequency, making it the clear dominant direction, while ideal offshore S-SSW-SW-WSW flow falls to 22%. With sea surface temps still cool at 14.4°C and air temps warming slightly to 13.5°C, the surf quality is all about timing - pick the southerly offshore windows and you will be rewarded with classic, lined-up Almagreira waves.
