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.

August: Peak Summer Flatness

August offers no relief from the summer doldrums, with an average wave height of 0.5m and a period of 4.0s. Swell is dominated by WSW (20.5%), SW (13.7%), S (13.4%), and WNW (11.5%). The WSW contribution is again the largest source of any swell, but 85% of all swell is under 0.5m. Wind conditions are slightly more onshore than July: S and SSE winds account for 15.3% of the time, while W and WNW winds dominate at 20.9%. Offshore N/NW winds are rare (around 5% total). The ideal wind stat drops to 7%—the lowest of the year. August is the classic Mediterranean flat spell. The only surf comes from distant storms in the southern Tyrrhenian, but they produce weak, short-period energy that gets murdered by the afternoon sea breeze. Early morning glass can occur, but there’s often nothing to ride. It’s a month for snorkeling, not surfing. The water is warmest of the year at 25-26°C.
