Santa Marinella - surf spot statistics

Best Surf Season (December - February)

The heart of winter delivers the most consistent swell to Santa Marinella’s south-facing shores. With average wave heights hovering around 0.9 to 1.0 meters and periods climbing into the 5-second range, you’ll find more frequent rideable conditions compared to the rest of the year. The North Atlantic’s storm track shifts south, feeding the Tyrrhenian Sea with pulses of S, SSE, and SW swell. Offshore winds from the north and northwest blow 11-12% of the time, creating clean, groomed faces—especially during high-pressure setups that deliver crisp N/NW winds. While the average isn’t huge, the combination of a solid south swell and a light offshore wind can produce surprisingly fun, punchy waves in the 1-1.5m range. Keep an eye on the NAO: a negative phase often funnels more cold fronts into the Mediterranean, ramping up surf potential.

Fair Surf Season (October - November, March)

The shoulder months offer a taste of winter’s energy without the full commitment. October and November see average swell heights of 0.7-0.9m with periods around 4.7-5.2s, while March maintains 0.8m and 5.1s. Swell directions are more variable, with S, SSE, and SW pulses still common, but the wind patterns become trickier. Offshore blows from N/NW are most reliable in November and March (approximately 10-11% ideal wind), but October can be plagued by onshore SE/SSE winds that blow 30% of the time. When the synoptic setup aligns—a deep low over the Gulf of Genoa with a trailing cold front—you can score clean, long-period swell from the SSW that wraps nicely into the bay. Expect periods of clean fun-sized waves mixed with windy, choppy days.

Low Surf Season (April - September)

From spring through early autumn, Santa Marinella goes into a deep surf slumber. Average swell heights drop to 0.5-0.7m, and periods shrink to 4.0-4.5s—typical of weak, short-period windswell. The predominant swell comes from S, SW, and WSW, but these are often accompanied by onshore winds from the same quadrants. Offshore wind conditions are rare, occurring only 7-9% of the time. The summer months (June-August) are especially flat and glassy in the mornings, but the only rideable waves are tiny micro-swell that might grovel on a log. April and May see slightly more energy from S and SSE, but the wave quality remains poor due to short periods and frequent onshore flow. For the dedicated surfer, these months are best reserved for travel, windsurfing, or enjoying the beach. The occasional thunderstorm or distant low can produce a brief spike, but consistency is lacking.

December: Midwinter Peak

December tops the charts with the highest average swell height of the year: 1.0m with a period of 5.2s. Swell energy is widespread, with major contributions from SSE (10.8%), SW (12.8%), WSW (11.2%), and NNE (7.4%). The NE and NNE components are less ideal but still add some background energy. What sets December apart is the frequency of swell above 1m: nearly a third of all waves exceed 1m, with a notable amount in the 1.5-2m range. Wind conditions are the most favorable of the year: offshore N (7.7%), NNE (12.4%), and NE (13.9%) winds dominate, though NE is not ideal, the N and NNE are. The total ideal wind (N, NW, NNW) is around 11%, but N and NNE together make up 20% of wind directions, often with speeds 10-30kph. This means more clean offshore days than any other month. The Mediterranean winter storm track is in full swing, and the NAO often turns negative, funneling Atlantic energy into the region. Look for deep lows in the Ligurian Sea to produce long-period S/SW swell with strong north winds behind them. December offers the best chance for firing surf at Santa Marinella—consistent, chest-to-head-high waves with pristine offshore conditions on the best days.
