Conditions at Salgueiros in March
March: Late-Winter Swell Meets Spring Transition
March is still firing, but the consistency starts to slip. Average swell height drops slightly to 5ft (1.6m), period to 12.0s, and the swell direction remains excellent - WNW at 42%, NW at 27%, W at 17%. The Portuguese coast can still see serious groundswell from late-season extratropical storms, especially when the NAO is negative and low pressure stalls near the Bay of Biscay.
The main difference is wind: favorable offshore windows fall to 39%, and the NNW wind share grows to 19% as the northern Atlantic high-pressure ridge begins to build. Good days are still easy to find, but the morning window becomes more important. Water temp is 13.7°C, air averages 12.4°C, and rain is still significant. A 4/3mm suit is still the call.
