Conditions at Playa Serena in December
December: Dry Season Mix and Clean Mornings
December closes the year with a classic dry-season pattern. Wind is strongly offshore, with NNW at 62.2%, N at 11.2% and NW at 11.0%, and ideal windows remain at 72%, giving Playa Serena plenty of glassy, groomed surface conditions. The swell, however, is a two-part story: SSW/SW/WSW still combine for about 63% of the energy, but N/NNW windswell reappears around 24% combined and average period slides back to 9.0s. Height averages 0.7m (2.3ft), mostly in the 0.5-1m (1.6-3.3ft) band. With rain dropping to 3.45mm/day, air temperatures around 25.8°C and water temperature at 28.3°C, December is a pleasant month for clean but inconsistent, short-period small waves. The north swell is mostly shadowed, but the SSW pulses that do arrive will be nicely groomed by the offshore flow.
