Andora - surf spot statistics

The surf conditions in Andora, Italy, vary significantly throughout the year, with the best months for surfers typically occurring during winter and early spring. From December to March, the swell activity is strongest, with ground swells making up 21–24% of the waves and wind swells contributing another 42–51%. Mean swell heights during these months range from 1.1m to 1.4m, offering the most consistent and rideable waves. However, wind conditions are generally unfavorable, with bad winds (onshore or cross-shore) dominating 85–88% of the time, making clean surf sessions rare. The shoulder months of November and April still see decent swell activity, with mean sizes around 1.0–1.2m, but wind conditions remain problematic. From May to September, surf potential drops sharply, with ground swells becoming scarce (3–8%) and wind swells weakening, while no-swell days increase to over 50%. Swell size averages a small 0.7–0.9m, and wind conditions worsen further, peaking in August–September with bad winds nearly 90% of the time. October marks the return of slightly better swells (1.0m), but winds remain unreliable. Overall, the prime window for surfers in Andora is December–February, when swell energy is highest, though finding good wind conditions requires patience and luck. Mid-year months are best avoided for serious surfers due to minimal waves and poor winds. For the most rideable conditions, target early winter while monitoring wind forecasts closely.

In September, Andora generally offers surfable but often small conditions with an average swell height of 0.9m and a modest 5.9s period. The best swells come from the SSW and SW directions, which produce the most rideable waves in the 0.5-2m range, occasionally reaching 2.5m. These directions account for the majority of surfable days, though larger swells above 2.5m are rare. Westerly swells (W, WNW) can bring more size but are less frequent and often accompanied by wind issues. Wind conditions are mixed—only 11% of the time do they align favorably for surfing, typically light offshore winds from the ENE to SE. Stronger onshore winds from the W and SW can create choppy conditions, especially when paired with larger swells. Overall, September is a decent month for intermediate surfers when local winds cooperate, but expect mostly small to mid-range waves with occasional clean sessions if timing aligns with lighter winds and SSW/SW swell angles.
