Bogliasco - surf spot statistics

Best Surf Season (November - February)

The heart of winter unleashes the North Atlantic's fury upon the Ligurian coast. November through February consistently deliver the highest average swell heights (0.8-0.9m) and the best wave periods, often punching into the rideable 6-9s range. More importantly, this is when the offshore wind window is at its peak, with ideal northerly and north-northeasterly winds blowing over 40% of the time (peaking at 47% in December). The clash of cold continental air and mild Mediterranean sea surface temperatures creates frequent low pressure systems that track across the Gulf of Genoa, generating the preferred SW to SSW swell that wraps into Bogliasco's south-southwest facing beach. When a strong high pressure ridge builds over Central Europe, it funnels crisp, offshore N-NNE winds and groomed lines of swell – that's when this pebbly stretch truly fires.

Fair Surf Season (March, April, October)

These shoulder months offer a mixed bag. March and April see a gradual decline in both swell size and consistency, with average heights dropping to 0.7-0.8m and ideal wind percentages falling to 24-31%. October marks the early return of winter patterns, with significant SW and SSW swell contributions (totaling over 35%) and a jump in ideal wind to 31%. However, the wave period remains marginal (5.0-5.4s), meaning you'll need to be selective. The challenge here is that the same low pressure systems that bring the best swell often also bring southerly onshore winds. Your best bet is to watch for post-frontal conditions where winds shift to the north.

Low Surf Season (May - September)

The Mediterranean summer is no friend to Bogliasco's peaks. From May through September, average swell heights bottom out at a meager 0.4-0.6m, and wave periods rarely crack the 5-second mark. The dominant SW swell direction is accompanied by oppressive onshore winds from the SSE to S quadrant, with ideal offshore wind percentages plummeting to just 10-20%. The Ligurian Sea becomes a millpond under the influence of the Azores High, leaving the lineup starved of energy. Occasional weak pulses of infragravity swell or distant storm activity might provide the rare rideable wave, but for the most part, this is a time to store your shortboard and enjoy the Italian Riviera in other ways. If you must surf, target early mornings with local thermal breezes that can offer slight offshore relief from the N-NNE direction.

January: The Deep Winter Engine

January is prime time for Bogliasco as the North Atlantic low pressure train rolls through the Mediterranean. Average swell height sits at 0.9m with a period of 5.6s, but don't let that low average period fool you – when a proper storm sets up over the Gulf of Genoa, it can deliver punchy, 8-10s SW groundswell. The dominant swell direction is SW (28.8%), with significant contributions from SSW (11.6%) and surprisingly from NNW (15.0%) – though NNW swell is less optimal due to its northerly approach. The wind is your ally here: ideal offshore conditions from N (31.1% of the time, mostly 10-20kph) and NNE (18.2%) keep the waves clean and lined up. However, watch for onshore winds from SSE (10.0%) and S (8.5%) that can quickly turn things choppy. The key is to track cold fronts: as they sweep through, winds clock to the north and the SW swell arrives with texture. With 46% of the time in ideal wind, January offers the best combination of size and clean conditions in the area.
