Il Porto - surf spot statistics

Best Surf Season (October - March)

During these months, the Mediterranean springs to life as extratropical cyclones and frontal systems sweep across the basin, generating consistent S, SSW, SW, and WSW swell that aligns perfectly with Il Porto's south-southwest exposure. Average wave heights climb to 0.8-1.0m with periods averaging 5.0-5.2s, often pushing punchy, rideable waves. Meanwhile, the frequency of offshore winds from N, NNE, NE, and ENE peaks at 12-13% of the time—especially during high-pressure setups over central Europe—creating clean, glassy conditions. This is the prime window for scoring fun, rippable surf, with occasional bigger swells (1.5-2.5m) firing when storms align.

Fair Surf Season (April - May & September)

Transitions bring a mixed bag. In April and May, the North Atlantic storm track weakens, and average swell heights drop to 0.6-0.7m with shorter periods around 4.5-5.0s. While S/SW swell still arrives, it's often smaller (mostly under 1m) and suffers from increasing onshore winds as thermal low pressure builds inland. September sees a similar pattern: the first autumn storms reawaken the swell window, but periods remain short (4.3s average) and wind consistency is spotty. Look for early mornings with NNE breezes to catch clean, waist-high waves—these months require patience but can deliver surprising gems.

Low Surf Season (June - August)

Summer in the Med means high pressure dominance, minimal storm activity, and a severe drop in swell energy. Average wave heights bottom out at 0.5m with periods of 4.0-4.2s—the definition of choppy, micro surf. The prevailing winds shift to S, SSW, SW and WSW (onshore) due to sea-breeze patterns, ruining what little wave shape exists. Offshore wind frequency plummets to just 6-7%, making clean waves extremely rare. Most days are flat or merely thigh-high slop. Unless you're a grom with a foamie, your best bet is to save the wax for the autumn return.

December: Winter's Peak Potential

December leads the pack in average swell height (1.0m) and period (5.2s). SW (12.8%) and WSW (11.2%) are the workhorses, along with SSE (10.8%) and S (8.6%). The ideal S-SSW-SW-WSW quadrant contributes over 35% of all waves. Notably, there are higher percentages at the 1.5-2m and 2-2.5m brackets: SW has 1.6% in 1.5-2m and 0.9% in 2-2.5m; WSW has 1.8% and 1.3%—these are the firing, heavy conditions. Offshore wind frequency matches the peak at 13% (NE 13.9%, NNE 12.4%). The combination of strong lows tracking across the northern Med and a robust Siberian high often creates a pressure gradient that funnels cold, offshore NE winds onto the Adriatic coast. This is prime time for Il Porto: expect solid, powerful waves in the 1.5-2.5m range with clean, groomed faces when the wind cooperates. December is the month to keep your wetsuit ready.
