Conditions at Cabedelo do Douro in March
March: Transitional but Still Chunky
March stands at the threshold between winter and spring. The North Atlantic is still active enough to produce an average swell height of 5.2ft (1.6m) and a period of 12.0s, and the directional spread remains excellent: WNW 42.2 percent, NW 26.6 percent, W 16.9 percent, WSW 4.1 percent. Solid 3.3-6.6ft (1-2m) waves are the norm, with a decent block of 6.6-8.2ft (2-2.5m) sets showing up on the bigger WNW/W swells.
The wind picture becomes less reliable, however. Ideal offshore conditions drop to 37 percent, while the northerly regime begins to strengthen: NNW wind reaches 18.2 percent and NW 7.0 percent. This means more bumpy, sideshore/onshore days as spring approaches. With air temperatures rising to 12.4°C and water still cool at 13.7°C, the surf still has winter power, but you need to pick the easterly wind windows to get Cabedelo at its best.
