Conditions at Mundaka in November
November: Heavy Water Season Arrives
November is deep autumn, and the Bay of Biscay is starting to feel properly wintry. Average swell height is 6ft (1.8m) and the average period sits at 11.7s, with the bulk of the energy coming from NW (33.1%) and WNW (23.0%). A significant amount of this swell is in the 5-8ft (1.5-2.5m) range, and the strongest NW windows can push past 8ft (2.5m) on the outside. Mundaka's bar is now frequently holding real slabs of water, and if the wind plays ball, the left can be both heavy and endless.
Wind, though, is increasingly volatile. Offshore SSW (11.3%) and S (10.2%) flows still offer plenty of clean windows, but W and WNW winds combine for about 20%, bringing bouts of soaking rain and onshore storm surf. The key to November is synoptic timing: surf the fronts, don't fight them. Ideal wind occurs 26% of the time. Air temperatures drop to 12.9°C, water temperature to 16.0°C, and precipitation jumps to 4.87mm/day-the wettest month in the data. November rewards the dedicated surfer with some of the most powerful, jade-green Mundaka days of the year.
