Conditions at Guethary in October
October: The Main Event Begins
October is a classic turning point on the Basque coast. Average wave height jumps to 4ft (1.3m), period to 11.3s, and the Atlantic storm track starts sending regular packets of WNW/NW groundswell. The direction data is superb: WNW 41.2% and NW 42.1% together form over 83% of the wave spectrum, with a useful W contribution at 2.7%. The heights are now spread across the fun-sized 2-3ft, solid 3-5ft, and pumping 5-8ft categories, so there is something for every kind of surfer.
Ideal wind frequency rises to 41%, and the SSW, SW and WSW sectors become reliable players again, adding close to 18% of clean surface between cold fronts. Water temp is 18.4°C and air temps 16.1°C - autumn wetsuit territory. This is the month when Guethary's sandbanks start lighting up on a regular basis, especially when low pressure deepens over the North Atlantic and sends long-period swell straight into the northwest-facing bay.
