Conditions at Ondarreta in February
February: Full-Bore Winter Groundswell
February is the twin of January for raw ocean energy. Average swell remains 2.1m (7ft) with an average period of 12.7s, and the Atlantic storm track is still aimed at northern Spain. The swell distribution shifts slightly; NW becomes the clear leader at 31.2%, WNW follows at 25.8%, and NNW chips in 9.7%. This is serious groundswell, and any NW/NNW pulse over the 10-second mark will put size and power on the sandbars.
Offshore wind is still your friend. The ideal-wind factor is 44%, with the southern quadrant supplying S winds 16.3% and SSW winds 7.8%; SSE at 8.7% adds variety as well. Yet February can be stormy in a different way: rainfall averages 3.11 mm/day and lows have been recorded down to -1.7°C. Water temps are the chilliest of the year at 12.5°C. When the low pressure moves away and a south wind fills in behind the front, the result is some of the most powerful, grinding winter surf Ondarreta has to offer.
