Caribbean in Winter for Remote Work: Which Island Is Actually Warm and Dry?

Which Caribbean island is best from December to April?

It depends on whether you mind cool or mind showers more. All four bases we track are dry compared with their summers, but they are not alike. Here is January, the middle of the winter window:

Two stories sit in that table. In millimetres San Juan is clearly the wettest, more than twice Nassau, with Barbados next and Santo Domingo and Nassau driest. In how often it rains the order flips: Nassau has the most rain days and the lightest totals. Take the small islands' rain-day shares with care. Barbados and San Juan are small trade-wind islands, where the weather model behind the shares misses rain, so those shares are probably too low and the gap to Nassau smaller than it looks. The millimetres are not affected: they come from satellite and rain-gauge data. Trade-wind rain comes as quick showers, not long wet spells, but if you plan outdoor time by the hour, the difference matters.

Is Nassau too cool for a "Caribbean" winter?

For some people, yes. Nassau and the Bahamas sit north of the tropic, so winter highs are 25° in January and February, with nights near 21°. That is pleasant for walking and working on a terrace, with a light layer in the evening, and not hot enough for long beach afternoons every day. Barbados is 3 to 4 degrees warmer by day and about 3 degrees warmer at night, and the airport stations show a gap of about 3 degrees by day too.

Nassau's trade-off is more rain days, not more cloud: in February it has rain on about 5 of 28 days, and cloud covers 38% of the sky, about the same as Barbados and San Juan. So the case for Nassau is mild weather you can work outside in, not a drier calendar than the others.

Where does Barbados fall short?

Not in heat, not in total rain from February to May, and on paper not in how often it rains: February has rain on about 1 of 28 days, the fewest of the four. That is the number to trust least, for the reason above, so expect passing showers on more days than it says. Barbados's strength is how long the dry season lasts: February to May are its driest months (40 to 56 mm a month), and its winter starts wetter than Nassau's or Santo Domingo's, at 78 mm in January and 102 mm in December. June is where the change starts, then the rain builds through the autumn, with October the wettest.

How do San Juan and Santo Domingo compare?

Both have a 28° high in winter, about the same as Barbados. San Juan has more rain days than Santo Domingo all winter (about 4 of 31 in January against about 2) and is about twice as wet in millimetres in January and February. It stays between about 97 and 136 mm a month from January to June, so it never has a dry season. Santo Domingo is the drier of the two in January and February but turns in April (93 mm, rain on about 7 of 30 days), and May is wetter again.

The practical rule for a long stay: Santo Domingo is a good January to March base, and from April expect more rain each month. San Juan is steadier but never really dry.

When does the wet season start, island by island?

Not on the same month, as the strip shows.

In May Nassau and Santo Domingo are clearly wetter than they were in March, San Juan somewhat so, while Barbados is still comparatively dry, so it is the island to pick if you want to stay into May. At the other end, each island's wettest months fall between August and October. The Atlantic hurricane season runs from June to November (NOAA); December to April is outside it. We do not measure storms, only rain, heat and cloud, so check forecasts for any trip in that window.

What would we do?

Pick the month you will actually be there, then the island. A December arrival suits Nassau and Barbados: Nassau is drier in millimetres (60 mm against 102 mm) but has more rain days, and Barbados is warmer. March suits all four. April is where the choice narrows, because Santo Domingo and San Juan are already wetter and Barbados and Nassau are the drier picks. Need real beach heat in the same months and can fly further? See where is warm in January and where is warm in February; Goa and Southeast Asia are drier still.

Which island suits you?

• Barbados

  Dry February to May, with quick showers on more days than our rain-day share shows.

  Suits: heat, and staying into May

• Nassau

  Mild weather you can work outside in, the most rain days, the lowest winter totals.

  Suits: pleasant terrace weather from January to April

• San Juan

  Warm and steady, with no real dry season.

  Suits: a big nomad scene, if you accept some rain

• Santo Domingo

  Dry in January and February, turning in April.

  Suits: january to March, then move on
