Conditions at Somo in October
October: Autumn Roar Returns
October is when the North Atlantic roars back to life. Average swell height jumps to 5ft (1.6m), the average period stretches to 11.3s, and ideal wind shoots to 50% - nearly double the summer rates. The dominant direction is NW at 50.3%, supported by WNW 17.1% and NNW 14.2%. The distribution is much healthier: a large cluster sits in the 3-8ft (1-2.5m) range, with the first serious storm swell of the season starting to appear. Wind patterns shift favorably as S and SSW winds increase; this is when Somo's famous combo of solid north groundswell and offshore southern winds becomes more routine. Air temps drop to 16.4°C, water temp is still pleasant at 18.4°C, and rain increases to 3.14mm/day. October is one of the finest months of the year on the Cantabrian coast.
