Because the island is influenced by two monsoon seasons, choosing the right month can shape your travel experience.

Understanding Sri Lanka's Climate

Sri Lanka has a warm tropical climate year-round, but two monsoons affect different parts of the island at different times:

• Southwest Monsoon (May–September): Affects Colombo, Galle, Bentota, Mirissa, and the hill country.

• Northeast Monsoon (October–January): Affects Trincomalee, Batticaloa, Arugam Bay, and the northern region.

Because the monsoons alternate, there is always a sunny region available no matter what month you travel.
