Conditions at Serapo in December
December: Peak of the Mediterranean Season
December is Serapo's most promising month on paper and often in practice. It posts the highest average swell height of the year at 3ft (0.9m), the longest average period at 5.6s, and the best ideal wind score at 39 percent. The wave rose is dominated by W and WSW, but the SSW, SW and S quadrants are active enough to keep the beach facing into genuine, rideable swell. When a vigorous Genoa low passes through the western Mediterranean, the Tyrrhenian can spike into the 5-8ft (1.5-2.5m) range for a few hours, and a following N-NNE wind can leave Serapo surprisingly clean and lined-up. Water temperature is around 16.5°C (61.7°F), air temps average 12.8°C (55°F), and rain is frequent but punctuated by bright, crisp post-frontal windows. If you want to score Serapo, December is the month to plan around.
