The central highlands can be significantly cooler throughout the year, so you'll need warmer clothes here. Lightweight rainwear is also recommended any time of year.


Sri Lanka is an island off the southeast coast of the Indian state of Tamil Nadu. It is separated from India by the Indian Ocean, in which lies the chain of islands called Adam's Bridge. Sri Lanka has an irregular surface with low-lying coastal plains running inland from the northern and eastern shores. The central and southern areas slope into the hills and mountains ranges of the Central Highlands. The highest peak is Pidurutalagala, which reaches an altitude of 2,524m (8,281ft).

The country’s coast consistx mainly of beaches and bays, with rocky cliffs in the northeast and southwest. Due to the southwestern location of the mountain range, precipitation is heavily weighted towards this area, with the the northern and eastern parts fall in the rain shadow of the Central Highlands. The wettest parts of the country in the south and west receive around 4,000mm of rainfall annually. There are two major national parks, in the northwest and southeast, designated as such to protect the immense biodiversity of the country’s wildlife.
