Andora - surf spot statistics

Best Surf Season (October - March)

The Ligurian winter fires up Andora's south-facing coastline as a series of deep Atlantic and Mediterranean low-pressure systems roll through. During these months, the average swell height hovers around 0.5-0.6m with periods in the 5-6s range, but the real quality comes from the prevalence of offshore N to NNW winds — blowing cleanly out of the Alps and creating glassy, groomed waves. The dominant SSW swell direction (25-40% of all swell) aligns perfectly with the beach's Süd-Süd-Ost exposure, delivering punchy, rippable lines. When a strong mistral or tramontana sets in, expect long-period groundswells from the S and SW that wrap into Andora with power.

Fair Surf Season (April & September)

These shoulder months see a transition in the regional weather pattern. April still receives a decent share of SSW swell (31% of the total) but the offshore wind reliability drops to just 11%, with more onshore flow from S and SSW spoiling the surface. Swell heights average 0.5m and periods slip to 5.3s — fun-sized but inconsistent. September benefits from the first autumn storms stirring the Med, pushing average heights back up to 0.4m and periods to 4.5s, but again only 8% ideal wind. Keep an eye on the charts for a passing cold front that could align the winds just right.

Low Surf Season (May - August)

The summer months are dominated by a stubborn high-pressure ridge over the Mediterranean, leading to weak, short-period windswell. Swell heights average a meager 0.3-0.4m and periods barely reach 4.5s, producing mostly choppy, micro conditions. The wind regime switches to frequent S and SSW breezes (often onshore), with ideal wind percentages bottoming out at 6-9%. While Andora delivers a few fun, groveling sessions during a rare sea breeze front, this is the time to explore other regions or focus on surfing the early mornings when the thermal winds are calmest.

October: Autumn Awakening

The North Atlantic roars to life during October, and the Ligurian Sea feels the pulse. Average swell height jumps to 0.5m and period to 5.0s, with SSW swell at 23% and SW at 13%. The real improvement is in the wind: offshore N winds blow 28% of the time, and NNW at 9%, giving a 37% total window for clean conditions — up from 27% in September. This combination of increasing swell and more frequent offshore flow means Andora starts to fire regularly. Storms in the Bay of Biscay or over the western Mediterranean send S and SSW groundswells that can see the 1.5-2m 'pumping' range. When a strong mistral wind (N-NW) sets in after a low passes, the waves are glassy, hollow, and make the most of the beach's favorable exposure.
