Conditions at Bico in March
March: Transitional Power
March is the last full month of prime winter conditions at Bico. The average swell eases slightly to 1.7m (5-6ft), but the period remains long at 12.4s, so even smaller groundswell packs a serious wallop. The swell direction is split almost evenly between WNW (32%) and NW (31%), with W (14%) in the mix - ideal for this northwest-facing stretch.
Ideal wind drops to 29%, a sign that the Azores High is starting to flex. The NNW onshore breeze becomes more persistent (24% of all winds), especially in the afternoon, but mornings often still deliver clean conditions. Air temps warm to 14.0°C on average, water temps sit at 15.0°C, and precipitation eases to 1.72 mm/day. March is a great month for reliable, hollow winter-esque waves before the spring energy fade truly begins.
