When is the best time to go to Sri Lanka?

The best times to visit Sri Lanka depend on the chosen destinations. Thus, the period from December to March is favorable to discover the capital Colombo and the communities located west and south of the country. During this time of year, one will have the opportunity to go snorkel diving in peace because the beautiful sunshine and an almost ideal water temperature enlighten and liven the days. Furthermore, this ideal period is also favorable for sightseeing in the center of the country.

In order to best discover the northern and eastern parts of Sri Lanka, choose the period between May and September. Although the vast monsoon season is in full swing on the western side of the country, the rest of the territory is spared by the rain, thanks to the geography of the Ceylon island.

If you wish to explore this beautiful island combined with its many attractions while distanced from the large crowds of tourists, pick a period that does not coincide with the school holidays. This will be the best opportunity to visit Sri Lanka, all while sparing your wallet.

Climate and Weather in Sri Lanka

Located at the heart of the Indian Ocean, just off the coast of India and not far from Indonesia, Sri Lanka is a country of equatorial or tropical climate, with a warmth that prevails from morning to night, without any interruption. The latter is still tempered by the presence of ocean winds. Humidity also reigns over most of the territory. However, the weather is heated among the plains or on the coast, as it is in Trincomalee and Jaffna but the mountainous areas on the other hand experience more bearable temperatures.

Sri Lanka: Nuwara Eliya, Sri Lanka

Tropical, the climate of Sri Lanka therefore faces two major monsoon periods. During the wet season, the country is covered in many rains that are usually followed by very cloudy periods. The main hazard of this monsoon season lies on the coast of the country, as the underwater currents are often very dangerous at this time of year.

The great monsoon season plagues the entire southwest of Sri Lanka, especially towards the capital, Colombo, from the months of May to late August. The country undergoes a humidity level of around 95% and is covered by a very moist heat. Meanwhile, the early monsoon season which does not occur every year, rages from October to late January on the east coast just as it does in Trincomalee.

Outside of these somewhat troubled weather periods for the country, the temperature is quite pleasant. While the rain still remains fairly common, other than between late January and April which is described as the driest period of the country, the climate of Sri Lanka does enjoy beautiful sunny periods.
