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.

June: Flat and Fickle

June hits the summer slumber with an average swell of 0.4m and a miserable 4.4s period. SSW swell remains the biggest slice at 40%, but almost all of it is under 0.5m. The wind picture is even worse: ideal offshore wind frequency bottoms out at 8%. Light onshore S and SSW breezes dominate, creating bumpy, weak waves. The sea breeze regime takes over, blowing from the S-SSW right into the beach during the afternoon, trashing what little swell exists. Early mornings can still offer a small, clean window if the night-time land breeze (from the N) manages to smooth out the surface on a rare, small pulse of S-SSW swell. But honestly, this is a month to travel north or surf other spots.
