Average temperature for the ABCs year-round is a perfect 28°C (82°F). High noon is a bit warmer and at night it can get breezy, but mostly you’ll be fine in shorts and T-shirt. The islands are fairly dry, averaging a little over 1in (2.5cm) of rain per month. Much of this falls from September to early December. The islands usually miss the Caribbean hurricane season, although a couple passed to the north in 2007 and dumped a lot of water. As always, when you go depends on how cold you are. If you just have to warm up December to April, then you can join the crowds during high season. Otherwise, the islands are more accessible and rates much cheaper other times of the year. The high season for cruise ships runs October to April. Outside of these times the port towns can be almost sleepy.
