When is the best time to visit Sri Lanka?
Sri Lanka generally offers warmth and sunshine throughout the year.
Whilst planning your holiday, it’s important to remember that the world’s weather has a funny habit of not sticking to script, and this is never truer than in Sri Lanka. You will often be blessed with clear blue skies in what should be rainy season, or with torrential downpours in the middle of the dry season. Therefore you would do well to consider a whole host of other elements (ie seasonal airfares, school holidays etc) in addition to the weather when making your plans.
If you know which side of the island to focus on in any given month, then Sri Lanka can lay genuine claim to being a year year destination.
The weather in Sri Lanka is dictated by two monsoon seasons. The East Coast comes into season between March and September, while the South Coast is at its peak between November and March. The rest of the year is sunny and dry. Temperatures are fairly constant year round, with coastal regions enjoying average temperatures of 25-30°C and the highlands 15-18°C on average.
Unquestionably, the starting point when planning your trip in Sri Lanka is understanding the two monsoon seasons. The south-western monsoon brings rain to the south-west of Sri Lanka between May and September, while the dry season in this region runs from December to March. In the north and eastern coastal regions of the country, the weather is influenced by the north-eastern monsoon, which brings wind and rain between October and January, and drier weather between May and September.
There is also an inter-monsoonal period during October and the first half of November, when rain and thunderstorms can occur across the island. This clears up as December nears, with conditions getting balmier by the day during the second half of November.
As with many South-East Asian destinations, the period from December to mid-April is considered the peak season for overall weather and therefore overall visitor numbers. Whilst there is good reason for this, there are equal benefits to travelling outside of this period, with the shoulder season often providing the best of both worlds; namely great weather and a lower visitor numbers.
In general when it does rain, it’s unusual for the rain to last all day, with downpours tending to be short and sharp, often with a number of inches falling in just a matter of minutes. In extreme cases this can lead to localised flooding, which when severe can require last minute alterations to your travel plans... one of the highlights of travelling in Asia!
The East Coast
Passekudah, Trincomalee, Arugam Bay, Batticaloa, Nilaveli, Kuchchaveli
Sri Lanka’s east coast comes into its own while the rest of the island is experiencing monsoonal rains. Influenced by the north-eastern monsoon, the best weather is from April to September, with the monsoon running from October until January.
Presently the infrastructure and resort development are minimal, but things are changing fast, with a host of luxury hotels planned in the coming years. If you are happy with more basic beach accommodation, the east coast's summer offers a truly exceptional opportunity to enjoy some of Asia’s least developed beaches.
Kandy & Tea Country
Kandy, Ella, Nuwara Eliya, Haputale, Hatton, Adam's Peak
Kandy sits at a far lower altitude than the 'Tea Country' and because of this can expect to enjoy higher temperatures and lower rainfall than in the hills to the south. Your journey from Kandy & The Cultural Triangle climbs an elevation of 700 metres, so you feel a drop in temperature as you climb. The weather in the Tea Country is influenced by both monsoons, the result of which is a climate somewhat reminiscent of a Scottish autumn for much of the year. Sitting at nearly 2,000 metres above sea level, the region is much cooler than elsewhere in Sri Lanka.
December marks the beginning of the Adam's Peak pilgrimage season, which runs throughout the dry season until May.
Colombo & the West Coast
Bentota, Colombo, Negombo, Kalpitiya
With the west coast’s weather governed by the south-western monsoon, the best weather is expected between late November and April. Average temperatures throughout rarely drop much below 30 °C, but at certain times high rainfall and stormy conditions mean that your idyllic beach plans are best made elsewhere.
Rainfall is at its highest between June and September, although August is often an exception with much lower rainfall.
Galle, Weligama, Mirissa, Tangalle, Yala National Park
The beaches in the south western corner, close to Galle, experience similar weather patterns to the west coast, with the best weather expected between late November and April. Further east, beyond Yala NP, the weather can also be influenced by the north-eastern monsoon, with its higher rainfall from October to January, and dryer weather from May to September. As with much of Sri Lanka, September & October can also see heavier rain, although by November blue skies are expected once again, with good weather expected through till May.
The Cultural Triangle
Dambulla, Anuradhapura, Sigiriya, Minneriya National Park
Many of Sri Lanka’s cultural highlights, including no less than five UNESCO sites, including Dambulla, Anuradhapura and Sigiriya, are located within this ‘dry zone’. Aside from a high rainfall in November and December, conditions remain fairly arid throughout the year, although visitors during June and July may experience the hot, strong winds that help keep the south-western monsoon at bay.
