Conditions at Santa Marinella in July
July: Peak Summer Flatness, With Dawn Patrol Hope
July is statistically one of the flattest months for surf at Santa Marinella. The average swell height stays at 1.6ft (0.5m) with a period of just 4.0s. The swell rose is dominated by WSW at 21.0% and SW at 14.3%, though these are mostly very short-period windswell and not favourably directed for the beach. The S, SSW and SSE sectors combine for around 30% of the swell, but nearly all of it is in the 0-0.5m (0-1.5ft) class. On the rare occasion that a summer thunderstorm drifts across the Tyrrhenian, it can kick up a brief SE/SSE windswell, but it is usually small and short-lived. Winds are largely thermal and afternoon-driven, with WNW at 12.4%, W at 9.8% and SSE at 9.0%. The ideal offshore window is 8%. Water temperature climbs to a warm 23.9C, air temperatures average 24.5C and precipitation is just 0.67 mm/day. Check the beach at dawn, when glassy conditions might line up the small leftover swell, but keep expectations low.
