Understanding Sri Lanka’s Weather
Sri Lanka has a tropical climate, meaning it’s hot and humid most of the year. The weather is influenced by monsoons, which bring seasonal variations in rain. Temperatures stay between 25°C and 30°C (77°F to 86°F) year-round in coastal regions, while the Hill Country (like Nuwara Eliya) is cooler, easily dropping to 16°C (61°F).
There are two main monsoon seasons. The southwest monsoon (Yala) runs from May to September, affecting the west and south coasts. The northeast monsoon (Maha) falls between October and January, targeting the north and east. The dry season, from December to March in the south and west, and May to September in the north and east, is usually the best time to visit. However, the rain doesn’t always mean bad news for travel. You’ll still get plenty of sunshine.
Best Time to Visit Sri Lanka
Sri Lanka’s weather works as a balancing act. When one side of the island is wet, the other is often dry. If you’re a beach lover, December to March is perfect for the southern and western beaches. If you want to explore the cultural triangle or head east, you’ll want to plan from May to September. Temperatures start cooling in the Hill Country around December, and the region stays relatively cool until March.
This gives you flexibility when planning—a trip with two completely different experiences at different times of the year.
Packing for Sri Lanka
If you’re visiting the beaches or coastal areas, pack light clothing. Breathable materials like cotton or linen will help you handle the heat. If you’re heading to places like Ella or Kandy, especially during December to March, pack a sweater. It’s noticeably cooler there, especially at night. Don’t forget to bring an umbrella or a good rain jacket if you’re visiting during the rainy season.
Sri Lanka’s Weather Month by Month
Sri Lanka’s Weather in January
January is one of the best months to visit Sri Lanka, especially the southwest areas. This is peak travel season because the weather is dry and sunny around Colombo, Galle, and down to Unawatuna. In the north and east, some rain might linger due to the still-fading Maha monsoon, but it’s not too bad.
Sri Lanka’s Weather in February

February continues the dry spell in the south and west, making cities like Galle and Hikkaduwa as popular as ever. The east and north begin to dry out, but it’s still slightly wet. The Hill Country stays pleasant, and you won’t need much winter gear, just something light for the cooler nights.
Sri Lanka’s Weather in March
March is when both the south and east coasts start getting hot. The rains have cleared for most of the island, but you’ll want to stick closer to the southern and western beaches if you want guaranteed sunshine. It’s a great time to visit places like Sigiriya or Polonnaruwa, but pack sunscreen; temperatures soar to around 33°C (91°F).
Sri Lanka’s Weather in April
April is a bit of a transition month. The southwest gets increasingly hot and humid, with occasional showers in the evening. Temperatures peak everywhere on the island, hitting nearly 35°C (95°F) in many places. However, it’s a great month for beach trips, especially as ocean conditions are calm.
Sri Lanka’s Weather in May
In May, the Yala monsoon starts, bringing rain to the west and south. If you’re headed there, expect short but intense showers. The east coast and the north, meanwhile, start their dry season. This makes areas like Trincomalee and Batticaloa excellent spots to explore.
Sri Lanka’s Weather in June
June in the southwest continues to be wet due to the Yala monsoon. If you’re in the Hill Country or coastal cities like Galle, expect more rainy setbacks. But, the east coast is enjoying sunny skies, making it the best time to visit places like Arugam Bay. Surfers love this season.

Sri Lanka’s Weather in July
July means more sunny days for the eastern beaches. Arugam Bay continues to have surf season in full swing. The Hill Country remains drier, especially towards Kandy and Ella. The southwest will keep having rain, but you’ll also get sunny breaks in between.
Sri Lanka’s Weather in August
August sees light rains in the south and west. You can still enjoy plenty of sunshine, but you should expect some showers at random. The Hill Country is also wetter compared to July, but most days are clear in the morning. On the east and north, it’s still dry and warm, perfect for beach hopping or exploring Jaffna.

Sri Lanka’s Weather in September
September is the last official month of the Yala monsoon. It’s still wet down south, but this is a quieter month for travelers, and you’ll get good deals on hotels in places like Colombo or Galle. The northeastern coasts remain sunny and dry.
Sri Lanka’s Weather in October
October can be particularly unpredictable. It can often rain island-wide as the two monsoon systems overlap. While this doesn’t make it the best time for sunbathing, it’s a good month for budget travelers. Hotels are cheaper, and tourist crowds are thinner, especially in main tourist areas like Kandy and Colombo.
Sri Lanka’s Weather in November
November brings the heavier rains of the Maha monsoon to the northeastern regions. If you’re staying on the coastlines of Jaffna or Batticaloa, expect daily downpours. However, on the southwestern coast, the rains begin to lighten up, making this a great time to visit places like Hikkaduwa or Tangalle, before the peak tourist season truly begins.
Sri Lanka’s Weather in December
December is a fantastic time to visit Sri Lanka, especially for the southern and western coastlines. The Maha monsoon still means rain in the northeast, but Colombo, Galle, and the nearby regions stay relatively dry and sunny. End the year soaking in the sun on some of Sri Lanka’s best beaches.

Final Tips
The weather in Sri Lanka is unique in that whenever there’s rain in one region, there’s almost always sunshine in another. To make the most of your trip, pack light clothing for the heat, but always have a rain jacket and some waterproof shoes ready. Don’t forget sunscreen for coastal areas, as the sun can get very strong even during monsoon months.
If you want the most predictable weather for a beach holiday, December to March is your best bet on the south and west coasts, while May to September is ideal for the north and east. Choose your region wisely, and you’ll have a fantastic trip no matter the season!
