Laredo - surf spot statistics

Best Surf Season (October - March)

The North Atlantic cranks up a notch during these months, as the jet stream dips and spins up a relentless sequence of extratropical lows. For Laredo, this means a steady diet of NW to WNW swell — the golden range for this north-east-facing beach. Average wave heights hover around 1.8 to 2.0m, with periods often climbing into the 12-13s range, delivering powerful, long period lines that wrap beautifully into the bay. The icing on the cake? Offshore winds from the S to SW blow cleanly across the face on roughly 45-51% of days, thanks to the region's high-pressure setups over the Iberian Peninsula. When a -NAO pattern locks in, expect pumping, firing surf that makes Laredo one of the Cantabrian coast's go-to winter destinations.

Fair Surf Season (April - May & September)

As the climatological transition unfolds, the Atlantic storm machine winds down. April through May sees the average swell size drop to 1.1-1.4m, and periods shorten to the 10-11s range — still offering punchy, rideable waves, especially in the 1-1.5m sweet spot. The NW and WNW swells remain dominant, but the frequency of offshore wind dips to 36-37% as springtime thermal gradients increase onshore afternoon breezes. September offers a similar trade-off: a rising swell graph from the early season lows, with 1.2m average and 10.4s periods, paired with a modest 37% offshore window. These months are best for the flexible surfer willing to pick their moments between high-pressure blocks.

Low Surf Season (June - August)

Summer settles in with a vengeance, and Laredo feels the lull. The Atlantic storm track retreats north, leaving behind a NW windswell regime that struggles to push past the 0.9-1.0m mark for most days. Periods hover in the 8.9-9.3s range, meaning low energy, soft waves that rarely offer much push. The catch here is the wind: offshore flow from the south occurs only 30-31% of the time, while the dominant summer easterlies (E, ENE) create cross or onshore conditions that chop up the tiny swell. While there are the occasional fun-sized morning sessions before the sea breeze kicks in, the region becomes a background noise of small, grovelly surf. For serious swell seekers, this is the time to travel or take up a summer sport above the high tide line.

January: Winter's Peak Power

January delivers the heaviest punch of the year, with an average swell height of 2.0m and a period of 12.9s — solidly in the 'powerful, long period' category. The swell distribution is heavily skewed toward the NW (36.7%), WNW (18.6%), and NNW (10.8%) quadrants, which together account for over 66% of all wave energy. That's a symphony of north-westerly groundswell that Laredo, facing NE, intercepts with excellent refraction. Wave heights are split across the 1.5-2m (pumping) and 2-2.5m (heavy) categories, with a notable 1.3% exceeding 2.5m. On the wind side, offshore directions from the S (11.4%), SSW (13.4%), and SW (5.4%) combine for a 50% ideal wind percentage — the best of any month. When a deep low pressure spins up over the British Isles and a high ridges into Spain, the result is clean, hollow peaks marching down the bay. This is the month to charge.
