St. Barths
With more than 300 days of sunshine a year, packing for St Barths isn't tough; make sure your sunblock reserves never run dry and you've got enough fresh water to last all day at the beach, and you're set. During high season (mid-December through mid-April) the temperature rarely rises above 90. May through November brings the rainy season, though it rarely rains for more than a few minutes each day. Many resorts close in September—the height of hurricane season—and use the time to perform renovations.
