Weather in Sri Lanka

January is peak season in Sri Lanka, so demand and prices can be high. That makes it more important than ever to get the best advice about where the value lies.

Southern and western beaches enjoy lots of sunshine hours, with moderate humidity and temperatures around 30C, although a weakening north-east monsoon might still linger in the north and east, especially along the coast.

Colombo also enjoys one of its sunniest and driest months of the year. It is a good time to visit Kandy and the Cultural Triangle, although occasional rain can occur.

Hill-country temperatures are lower, averaging 20C in the day because of the higher altitude, and can make a refreshing change from the sun on the coast. It can rain here, although historical rainfall figures are relatively low.

Lots of sunshine, low rainfall, and relatively low humidity mean the beaches on the south and west coast are enjoying peak season with temperatures around 30C, so book early to ensure availability at your preferred place to stay.

In the north and east, the north-east monsoon is now reduced to a whimper and largely occurs in the evening.

Dry weather in the national parks makes it a great time to visit Yala, Uda Walawe, and Wilpattu. The capital, Colombo, also has its driest month of the year. The Cultural Triangle’s most famous sites will be busy in February, and temperatures are similar to the coast.

It is cooler in the hills, with maximum temperatures around 20C, but this is one of the driest months and a great time for exploring Nuwara Eliya and Ella or trekking in the Knuckles.

It is hotter now on the south and west coasts, with peak temperatures pushing above 30C and humidity slightly higher than earlier in the year, but you are unlikely to see much rainfall. The kite-surfing season brings extra life to the north-west beaches of Kalpitiya.

The Cultural Triangle, dry and hot now, can expect peak temperatures heading towards 35C with lots of blue skies. The capital, Colombo, is also at its hottest from March to May, but in March it remains largely dry.

March is also one of the finest months to visit the hill-country capital of Kandy and the peaks of the highlands. You can anticipate lots of dry, sunny weather, perfect temperatures heading towards the mid-20s, and less need for a light sweater on cool evenings.

It is also a good time to climb Adam’s Peak, although you have entered pilgrimage season, so it could be busier than normal. If Easter is in March, remember that pressure on accommodation will be particularly high, especially in the hills.

Throughout the month, the beaches on the south and west coast are still attracting sun lovers, especially over Easter, and temperatures often reach the mid-30s, around 5C higher than in December and January when the peak holiday season begins.

One of the main attractions of April weather in Sri Lanka is that the risk of bad weather is small wherever you travel in the country, although the south-west monsoon begins to introduce itself as the month draws to a close.

On the east coast, the holiday season begins to stir back into life, with rainfall now vastly reduced and every chance of blue skies and sunshine, as well as attractive early-season hotel deals.

En route to the east coast, the Cultural Triangle is predominantly dry, with temperatures around the mid-30s. If you plan to visit the cultural sites, it is best to plan your exertions for either end of the day.

In April, the weather in Kandy and the tea-clad highlands can be a joy. March and April are the warmest months of the year here, with temperatures reaching the mid-20s. As Sri Lankans also head for the hills to escape the heat, make sure you book early to secure the accommodation you want.

Galle and the beaches are likely to experience heavy bursts of rain, and the seas lose their tropical allure, but especially at the start of the month there is still occasional sunshine in between. The capital, Colombo, can also expect a dousing.

No matter. Sri Lanka weather in May does look kindly on some. You can find the best weather on the east coast. Rain is slight and temperatures approach 30C, so that is where the wise beach lover should head. The Cultural Triangle, dry and hot, is a perfect stopping-off point.

The eastern end of the south coast, in Tangalle and beyond, also has some of the lowest annual rainfall in Sri Lanka, so it is rarely out of season.

May in Sri Lanka’s hill country, especially in the south-west of the hills, can also be wet, although Kandy and the northern hills still largely escape the rain and can expect temperatures of 32C. That makes it easy to include some hill-country scenery in your holiday itinerary.

Beach settlements such as Nilaveli and Pasikudah are perfect for a relaxing beach holiday, and the weather en route in the Cultural Triangle is also dry with lots of sunshine.

The eastern end of the south coast, in Tangalle and beyond, also has some of the lowest annual rainfall in Sri Lanka, so it is rarely out of season.

Even during the south-west monsoon, it is possible to enjoy days on the south and west coast with just the occasional downpour. Low-season prices are attractive and the rain brings freshness to the air, although the beaches tend to shrink and sea bathing can be dangerous.

As well as the western and southern coasts, the south-west monsoon also brings rain and cold to the hills, where daytime temperatures can be as low as 15C.

Along with occasional heavy showers there are clearer blue skies. Prices, too, remain enticing, with excellent cut-price deals available.

For guaranteed sunshine, you cannot beat the east coast. On the beaches of Nilaveli, Pasikudah, and the like, the skies are blue for much of the time, the seas azure, and the sands shimmering. Tangalle and the far south-east can also expect dry, sunny weather.

Temperatures average a touch below 30C on the coasts, with the Cultural Triangle a little warmer and occasional dry breezes. In the hills, where the rain has eased, nights and early mornings are still surprisingly cool, with daytime temperatures around 15C.

Sri Lanka’s entire south and west coast region usually experiences a considerable fall in rainfall compared with early July and September, both of which can also provide decent amounts of good weather. Water sports are back in full swing and temperatures average around 29C.

It is also a good month to visit the capital, Colombo. Consider heading north of Colombo to places such as Negombo and Kalpitiya for some of the best west-coast weather.

The gorgeous east-coast beaches remain in high season and are often the first target of travellers whose priority is sunshine, then more sunshine.

Further north in the Cultural Triangle, temperatures remain high at around 32C, rainfall is at a minimum, and the dry breezes of the previous two months have subsided.

As you move through September, the approaching north-east monsoon begins to make itself noticed in many parts of the island, although most downpours tend to appear in the evening and days can still offer plenty of sunshine.

Sri Lanka’s east coast is expecting its final month of good weather, so if it is beach time you are looking for, head to Pasikudah and Nilaveli. As October nears, however, the sense is of peak season gradually departing. In the south and west, you can grab extraordinary deals and will still see sunshine along with bursts of rain.

The Cultural Triangle remains hot and more humid. Again, the most intense downpours tend to be at night, bringing life and freshness to the air. It is also a reasonable month to visit Colombo.

By September, it has been a long drought in the far south-east and Yala National Park is often closed at this time of year to allow animals to roam far and wide in search of increasingly scarce water supplies.

Whether it is erroneously referred to as the start of the north-east monsoon, or more accurately as an inter-monsoon period that can bring thunderstorms across the island, the whole country can experience widespread rain as well as sunny periods.

For holidaymakers who find tropical rain uplifting, and you do exist, that means cut-price deals abound, although travel can be disrupted and not all entertainment facilities will be open.

There are other attractions too. Mannar and Uda Walawe are good for migrating birds in October, and Wilpattu National Park also has much to commend it. With the best weather likely to be found in the Cultural Triangle, it is always possible to knit together an attractive itinerary.

The inter-monsoon rains gradually dry up and the peak holiday season is still a few weeks away, so attractive prices remain available and there is no overcrowding at the most popular attractions.

There is still plenty of rain across the country. But the second half of November is particularly kind to the capital, Colombo, and to west-coast resorts as far as Hikkaduwa. Once the inter-monsoon rains relent, humidity levels can be low and the temperature a few degrees cooler than normal. If you want to beat the rush and are most interested in this region, late November might represent your ideal Sri Lanka climate.

This improvement is unlikely to be found on the east coast, which is awaiting the arrival of the north-east monsoon, often impatiently if water levels are running low. Temperatures are lower in the Cultural Triangle, generally below 30C now, and although there may be rain it is rarely persistent enough on the central plains to damage travel plans. Watch out for rain in the hills and in Galle, where the inter-monsoon period persists.

That makes the period around Christmas and New Year the most popular time of year to visit the country and, not surprisingly, prices are at their highest.

December is a particularly sought-after time to visit Sri Lanka’s western and southern coasts, with dry, sunny days again a regular feature, the beaches rapidly filling, and entertainment in full swing.

Tourists also flock to the hills, although often in defiance of the rain, with the weather on these wonderfully verdant slopes often not settling until Christmas is almost upon us.

In contrast, Sri Lanka’s north and east are now affected by the Maha monsoon season. That rain spreads into the Cultural Triangle, but this area has comparatively low annual rainfall, so it rarely disrupts the main cultural sites.
