Conditions at Quepos in December
December: The Dry Season Lightens the Lineup
December brings the return of the dry season and the most favourable wind regime of the year. The average swell height eases to 1.0m (3ft) with a 12.1s period, but the frequency of clean, long-period SSW/SW swells remains decent - 88.3% of the energy comes from the SSW and the rest from the SW, keeping the wave quality high. This is classic long-period groundswell, groomed by offshore NE trade breezes.
Ideal wind conditions improve to 26%, and morning sessions often see offshore NE/ENE breezes that keep the small-to-fun waves glassy. Rain drops sharply to 2.82mm/day, air temps average 25.6°C, and water temps are 28.1°C. It's the perfect time to pull out a longboard, a fish, or a log and enjoy the clean, punchy little waves.
