Getxo - surf spot statistics
Getxo seasonal overview
Best Surf Season (October - March)
The North Atlantic swings into full production mode from October through March, delivering a consistent barrage of WNW to NW groundswells to Getxo's west-northwest-facing coastline. Average wave heights hover between 1.5m and 2.1m with long-period energy (11–12.8s) that translates into powerful, well-structured lines. Offshore wind percentages peak at 44–50%, driven by a dominant SSW to S flow that cleans up the swell beautifully. This is prime time for pumping, firing surf – a classic Basque winter.
Fair Surf Season (April & September)
April and September serve as transitional windows with average swell heights of 1.2–1.4m and periods around 10–11s. The swell quality remains respectable – mostly fun, rippable waves – though the size and power dip compared to peak winter. Wind statistics remain favorable, with 41–44% offshore conditions, mainly from the SSW and S quadrants. The crowds thin out, and clean long-period pulses still sneak in between summer lulls.
Low Surf Season (May - August)
From May through August, the North Atlantic storm track retreats northward, resulting in smaller, shorter-period swells. Average heights drop to 1.0–1.2m with periods around 8.8–9.9s – often choppy and grovelly. While NW groundswell still dominates, the energy is less powerful. Offshore wind percentages decline to 36–39%, and onshore sea breezes frequently spoil the shape. This is the season for small-wave gear and chasing the rare early-morning glass-off.

Conditions at Getxo in December
December: Winter Peak Premiere
December closes the year with average swell heights of 2.0m and a solid period of 12.4s. The NW (29.6%) and WNW (20.4%) swell directions produce a high percentage of over-1.5m waves (45% of total), making for firing, heavy conditions. Ideal wind frequency is 46%, driven almost entirely by S (17.4%) and SSW (21.1%) – a very reliable offshore signal. This month often brings powerful, long-period groundswells that wrap into Getxo with precision. Onshore winds are less of a problem than in previous months, with the dominant offshore flow keeping the waves clean. December is prime winter surf, consistent and powerful.
