December at a glance

What December is actually like

December is a lively, festive month. It is still one of the wetter parts of the year, but the rain often eases as the month goes on, and the town fills with holiday energy: music, visitors and a buzzing beach scene.

Northeast swells make December a favourite with surfers, and the famous Salsa Brava reef is at its best. Nights are the coolest of the year, which is a welcome change if you feel the humidity.

How much does it rain?

December averages around 350 mm, though it often trends drier toward the New Year. Expect a mix of showers and bright spells, and a sea that is more about surf than flat-water snorkelling this month.

Rain or shine, December keeps you busy:

• Watch or try surfing the season's northeast swells
• Take a chocolate tour or a cooking class between showers
• Enjoy the festive nightlife, music and Caribbean food in town

Crowds, prices and events

The festive season is peak time. Expect the busiest crowds and the highest prices of the year, especially from Christmas to New Year, so book your stay well in advance if you are coming for the holidays.

Is December a good time to visit?

If you want atmosphere, surf and holiday energy, December is a great time, just book early and accept some rain. For calm, dry snorkelling weather, the veranillo months suit better.

Key takeaways

December is festive, lively and surf-friendly, still wet but often easing late in the month, with the coolest nights and the biggest crowds. Book early, pack for showers, and come for the energy rather than flat-water beach days.
