Timor-Leste has a hot tropical climate with temperatures in Dili typically ranging from 20°C to 36°C year-round. The country divides into two distinct seasons, and choosing when to visit can make a significant difference to your experience.
The Two Seasons
Wet Season — December to April
Heavy rains arrive from December, continuing through to April. Flooding and landslides are common, and some rural roads — particularly in the mountainous interior and south coast — can become impassable. Travel is still possible, but plan with flexibility and check road conditions before heading off the main routes.
Dry Season — May to November
The north coast (including Dili) sees very little rain. The central mountains and south coast occasionally receive a shower, but generally the weather is clear and dry. This is the best season for diving, hiking, and overland travel.
Best Time to Visit
April to July is widely considered the ideal window — the wet season is ending, the dry season is establishing, temperatures are slightly cooler, and visibility underwater is excellent for diving.
September to December is the prime whale-watching season, as pods of sperm whales, blue whales, and other species migrate through the Wetar Strait between Timor-Leste and Indonesia.

Microclimates
Timor-Leste’s terrain creates significant variation in local climates. The north coast around Dili is hot and relatively dry. Drive inland and upward toward the central mountains (Ermera, Aileu, Ainaro) and it becomes noticeably cooler and greener. Head south and the landscape becomes more lush, with higher rainfall even in the dry season.
This diversity means that whatever time of year you visit, there is always a part of the country with good conditions.
