Conditions at Il Bunker in December
December: Peak Season - The Most Consistent, Cleanest Window
December takes over as the standout month at Il Bunker. Average swell height reaches the yearly maximum of 1.0m (3ft), the average period holds at 5.2s, and ideal wind conditions are present 20% of the time. Swell directions are led by SW, WSW, SSE, S and SSW. While no month produces large groundswell here, the repeated passage of low-pressure systems in the Gulf of Genoa and the western Mediterranean basin delivers steady, rideable short-period swell. The wind regime is significantly cleaner than the rest of the year: NNE, NE, NNW and N total over 46% offshore flow, the strongest offshore bias of the year. That combination makes for small but fun, rippable conditions more often than any other month. Water temperatures are 14.6°C, air temperatures 11.1°C, and precipitation is 2.87mm/day. For a spot with such modest averages, December is the month to chase.
