Most travellers come to T&T between January and March, during the Carnival season when the climate is at its most forgiving (25-30°C/72-87°F). By May, the dry season parches the lush landscape and bush fires often rage through the hills. The rainy season starts in June and lasts till December, but in September there's a dry spell known as the petit carem , an Indian summer of two to four weeks; it's an excellent time to visit, with flights at low-season rates. Tobago hoteliers hike rates during high season (mid-Dec to mid-April), as do Trinidad hotels during Carnival, but smaller hotels on both islands charge the same all year round.
