There is no single dry season. There are two shorter lulls, and rain is possible in any month.

The short answer

Two short lulls, not a dry season

Pick the window that suits the rest of your trip, then plan for showers.

Our take. If you can choose, aim for September or October: the Caribbean’s first lull, while much of the Pacific is in its second rainy period. For a trip across both coasts, February and March is when both are at their driest.
If your dates are fixed, go anyway. Keep beach and snorkel days for the clear mornings and a wet-day plan in your pocket.

The pattern

Three wet stretches, two lulls

The national meteorological institute (IMN) describes two rainy periods interrupted by relative minimums.

JFMAMJJASOND
RainiestLullRainy or transition
From November to February rain picks up, peaking in December and January as cold fronts push down from the north. About 40 per cent of the year’s rain falls in that spell.
From April to August or September a new rainy period builds, with a second peak in July as the trade winds strengthen. About 46 per cent of the annual total.

Long-term averages from 1961 to 1990; individual years differ. La Niña years tend to be drier and El Niño years normal or wetter, and the most extreme rain events cluster at the turn of the year. Roughly 2,500 to 3,000 mm falls in the southern Caribbean in a year, less than in the northern Caribbean.

Two coasts

Pairing the Caribbean with the Pacific

The two coasts follow different calendars, so timing a trip across both is a choice of overlap.

February and March: both coasts at their driest. September and October: the Caribbean is in a lull while the Pacific is wet.
The South Caribbean is about four and a half to five hours from San José by road. Options in San José to Puerto Viejo.

For wet afternoons, cacao farms and cooking matter less when the weather turns, and the three-day itinerary is built to move around it.
