Saint Lucia is a mountainous Caribbean island where the Pitons rise straight from the sea and rainforest covers the interior. Soufriere and the Pitons, the drive-in volcano, the capital Castries and the reefs around Rodney Bay and Marigot Bay are among its best-known places, along with Creole culture and food. December to April is the drier stretch for hiking and sailing; the wetter months at mid-year are hotter and storm-prone, with rain in short downpours.
Warmest month: September (30°C). Wettest: October (87 mm). Best overall score: February (7.4/10).
