Conditions at Oyambre in October
October: The North Atlantic Roars Back
The North Atlantic roars back to life in October, and Oyambre feels it immediately. Average swell jumps to 1.5m (5ft) with a period of 11.2s, and the long-period groundswell machine starts spinning. The wave rose is perfectly aligned: 49.7% from the NW, 17.3% from the NNW and 14.1% from the WNW. The stronger low-pressure systems crossing the Atlantic send regular pulses of 1.5-2.5m (5-8ft) swell into the Bay of Biscay, and the sandbars start to hold their shape again. This is the classic autumn ramp-up that surfers on the north coast of Spain live for.
The wind window improves dramatically, with ideal offshore flow at 38%. South and south-west winds bring workable, off-land windows between fronts. Water temp is still comfortable at 18.1°C, air temp averages 16.7°C, and rainfall increases to 3.14 mm/day. The challenge is timing the frontal passages, but when everything aligns, October produces some of the best waves of the year.
