La Roccetta - surf spot statistics

Best Surf Season (November - February)

The heart of winter brings La Roccetta to life as the Mediterranean responds to powerful low-pressure systems diving across the northern Tyrrhenian Sea. Average swell heights climb to 0.9-1.0m with periods stretching to 5.0-5.2s, often punctuated by longer-period pulses from the south and southwest that wrap directly into the south-facing beach. Offshore winds from the north quadrant (N, NNE, NE, NNW) blow cleanly across the lineup 11-12% of the time, creating groomed, punchy waves in the waist-to-chest high range. The combination of consistent S and SW swell and favourable wind directions makes this the prime window for quality sessions at this exposed sand-bottom break.

Fair Surf Season (March, April, October)

As the seasons transition, the Atlantic storm track begins to shift, and the frequency of strong S swell events drops off noticeably. March and October still offer occasional pulses in the 0.7-0.8m range with period around 4.7-5.1s, but the mix of wind directions becomes more variable. Offshore wind percentages hover around 9-11%, so clean conditions occur less often. April is the most marginal of the fair months, with average heights dipping to 0.7m and period shortening to 5.0s. Swell from the S and SW is still present, but the window for well-shaped, offshore-groomed waves narrows. These months reward patience – look for a strong pressure gradient setting up a northerly breeze and a solid S groundswell to score fun, rippable waves.

Low Surf Season (May - September)

Summer settles in with a dramatic reduction in wave energy. From May through September, average swell heights hover between 0.5-0.6m and wave periods bottom out at 4.0-4.5s, producing mostly low-energy, choppy conditions. The predominant swell directions shift to a broader south quadrant (SSE, S, SSW, SW, WSW), but these are often windswell from local sea breezes rather than true groundswell. Offshore wind from the north quadrant is scarce, occurring only 6-8% of the time, while onshore winds from the same directions as the swell (S/SW) dominate, particularly in the afternoon when thermal gradients kick in. The result is a long period of small, weak, and often wind-affected surf. Only the arrival of an occasional early-season gale can inject a fleeting pulse of rideable waves – keep the logs at hand and watch for those rare north wind days.

May: Low Energy, Sea Breeze Season Begins

May ushers in the low surf season with an average swell height of just 0.6m and a period of 4.5s. The wave energy is dominated by locally generated windswell from the S (16.9%) and WSW (15.4%), but nearly all of it is below 1m. The period is too short to produce any real power – think choppy, weak lines. Offshore wind opportunities shrink to 9% of the time, with the strongest offshore flows coming from the N and NNE. Meanwhile, onshore SSE winds (9.9%) and sea breezes from the west (WNW at 8.7%) create messy surface conditions on most afternoons. May is a grovel season; only a lucky alignment of a late-season low and a strong north wind can produce a session worth paddling out for.
