Sri Lanka Weather in May | Rainfall, Temperature & Travel Tips
Sri Lanka weather in May marks the beginning of Sri Lanka’s southwest monsoon season, bringing warm temperatures and increased rainfall to the southern and western regions of the island. Average daytime temperatures range between 25°C to 30°C, while rainfall can be heavy, especially in coastal cities like Colombo and Galle. However, not all parts of the country are soaked; eastern and inland areas like Arugam Bay and Udawalawe National Park often experience milder weather, making them excellent choices for travel during this time. This guide breaks down what to expect from May in Sri Lanka, with travel tips, regional breakdowns, and must-visit destinations.
Is May a Good Time to Visit Sri Lanka?
Yes, but where you go matters. May isn’t part of Sri Lanka’s high tourist season, which means fewer crowds and lower prices. However, it’s also the start of the southwest monsoon, bringing heavy rain to the southern and western coasts.
That said, not all regions are equally affected. The east and north of Sri Lanka, including Arugam Bay, Trincomalee, and Jaffna, stay mostly dry, sunny, and perfect for beach lovers and surfers. Inland areas like Udawalawe National Park also receive less rain than the coast, and safaris continue as usual, especially in the mornings when the weather is more stable.
If you’re flexible with your destinations, May can be a rewarding and peaceful month to explore Sri Lanka, especially for nature lovers and budget travellers.

Regional Weather Breakdown
Understanding the regional weather in Sri Lanka during May can help you choose the best places to visit.
Western & Southern Coast (Colombo, Galle, Mirissa)
May marks the peak of the southwest monsoon, bringing heavy rain and thunderstorms to the western and southern coasts. Expect high humidity and the possibility of flash floods. This isn’t the best time to visit the beaches in these regions, especially for outdoor activities.
- Tip: If you do visit, consider staying near indoor attractions or planning your trips for the morning hours before the rain sets in.
Hill Country (Kandy, Nuwara Eliya, Ella)
The hill country experiences cooler temperatures (averaging around 20°C), but it’s also one of the rainiest areas in May. Expect frequent showers, mist, and fog, especially in places like Nuwara Eliya and Ella. However, the lush greenery makes for scenic views.
- Tips: Bring a warm jacket and be prepared for wet conditions, but enjoy the cool, refreshing atmosphere of the hill country.
South Central Sri Lanka (Udawalawe National Park)
Unlike the coast, Udawalawe National Park experiences a relatively dry climate in May compared to other regions. While there may be occasional light afternoon showers, the mornings are usually sunny and ideal for safaris.
- Tip: Early morning safaris are recommended before the rain picks up in the afternoon. The park remains open year round, so even during May, you can enjoy seeing elephants and other wildlife without the heavy rain typical of the coastal regions.
Eastern & Northern Sri Lanka (Arugam Bay, Trincomalee, Jaffna)
The east and northern regions of Sri Lanka enjoy much drier conditions in May, with sunny, warm weather perfect for beachgoers, surfers, and cultural explorers. Arugam Bay becomes a hotspot for surfing as the sea is calmer.
- Tip: This is one of the best times to visit if you’re interested in outdoor activities like surfing, swimming, and exploring coastal towns.
What is the Monsoon Season in May?
May marks the start of the southwest monsoon season in Sri Lanka, which typically runs from May to September. This monsoon brings heavy rains and strong winds, mainly affecting the western and southern coasts of the island. These areas, including Colombo, Galle, and Mirissa, experience the most intense weather conditions, with frequent showers and high humidity.
However, Udawalawe National Park, located in the south central region, is less affected by the monsoon. While there might be some light showers in the afternoon, the area remains largely accessible, and safaris can still go on as usual. The park’s morning safaris are especially great for spotting wildlife before the rain sets in.
- Tip: The southwest monsoon benefits nature lovers as it refreshes the landscape, making the island lush and green. It’s an ideal time to visit the central and eastern regions, like Udawalawe, for a more tranquil and unique experience of Sri Lanka’s wildlife and nature.
