December is arguably the best month of the year at Bogliasco. Average swell height is 3ft (0.9m) with a 5.6s period, and the ideal offshore wind frequency peaks at 47%. The swell rose is packed with SW (26.6%) and SSW (10.6%) energy, while NNW (13.9%) and N (9.8%) provide plenty of locally generated windswell. The distribution also shows more heavy winter size: over 4% of swells exceed 6ft (2m), and a significant portion of SW swell falls into the 3-6ft (1-2m) category.
Wind conditions are superb for this coast. N (21.6%), NNE (19.8%) and NNW (14.5%) dominate, giving the beach offshore flow more than half of the month. SSE (8.9%), S (7.4%) and SE (6.1%) are much less common. Water temperature has cooled to 15.6°C, air averages 4.6°C, and precipitation is 2.60mm/day.
