Hondarribia - surf spot statistics

Best Surf Season (October - March)

The winter months deliver the most consistent and powerful surf at Hondarribia. The North Atlantic storm track fires up, sending frequent low-pressure systems across the Bay of Biscay. Average swell heights hover around 1.8-2.1m with long-period energy (10-14s) from the NW and WNW quadrants – ideal for this NE-facing beach. Offshore winds from the SSW to WSW blow clean and frequent, keeping the waves shaped and hollow. Expect pumping, firing conditions with occasional XL days when the fetch aligns perfectly.

Fair Surf Season (April & September)

These shoulder months offer a transition from winter power to summer lulls. Swell heights drop to the 1.3-1.5m range, and periods shorten to 10-11s. NW swell still dominates, but wind patterns become more variable. Spring and autumn low-pressure systems still produce rideable waves, and the chance of a long-period pulse remains. Wind ideal percentages hold near 31-33%, making for fun, rippable sessions when the timing is right.

Low Surf Season (May - August)

Summer brings a dramatic drop in both swell size and period. Average heights fall to 1.0-1.2m and periods shrink below 10s, resulting in weak, groveling surf for most of the season. The predominant NW swell becomes more windswell-like, and onshore northerly breezes (NNE, NE) frequently spoil the shape. While offshore wind percentages actually peak in May-June (37%), the lack of proper swell means only small, fun-sized waves on the best days. This is a time for longboarders and beginners, or for chasing the rare south-westerly swell window.

December: Deep Winter Storms

December rounds out the year with prime surf conditions. Average swell height is 2.0m and period 12.4s, nearly matching January’s power. NW (28.1%) and WNW (24.4%) are the primary swell directions. Wind ideal time is 30%, with southerly winds (S 15.2%, SSW 10.9%) providing clean offshore conditions. The winter storm track is in full swing, producing heavy, long-period groundswells. Waves are consistently in the pumping range (1.5-2.5m) and can reach massive proportions (>2.5m) during strong events. This is a month for experienced surfers to score world-class waves at Hondarribia.
