If you’re visiting in May, it’s best to expect mixed weather, warm temperatures, and occasional disruptions from early monsoon patterns.
Seasonal Highlights in May
- Vibrant Landscapes
The combination of heat and early monsoon moisture keeps the island green, especially in the Hill Country and Cultural Triangle. - Good Wildlife Viewing
Udawalawe and Wilpattu remain strong for wildlife sightings, and the landscapes look fresh after early rains. - Ideal for East‑Coast‑Focused Itineraries
If your trip is built around beaches and surf, May is one of the best months to head east.
Weather Overview
May marks the start of the southwest monsoon. The south and west coasts see more cloud cover, rougher seas, and frequent showers, especially in the afternoons. Swimming conditions become less reliable, and beach days are hit‑or‑miss.
The Hill Country remains one of the best regions for May. Mornings are cool and clear, while afternoons often bring short bursts of rain. The scenery is lush, and temperatures are comfortable for hiking. The Cultural Triangle stays hot and mostly dry, though humidity rises and early‑morning sightseeing is more comfortable than midday visits.
The east coast begins its season, but early May can still be inconsistent — conditions improve steadily toward June.

Places to Visit in May
May is a transitional month in Sri Lanka, with the southwest monsoon beginning on the south and west coasts, hot and mostly dry weather in the Cultural Triangle, cooler and wetter conditions in the Hill Country, and the east coast opening for its peak season. If you’re planning a trip in May, expect mixed conditions in the southwest, excellent beach weather in the east, and reliable sightseeing inland.
May is good for:
- Hill Country: Ella town, Kandy town, Nuwara Eliya
- East Coast (late May): Trincomalee, Pasikudah, Arugam Bay
- Cultural Triangle: Sigiriya Town for Lion Rock, Dambulla Cave Temples, Polonnaruwa
These regions offer the most reliable conditions throughout the month

National Parks in May
May is not a peak safari month, but some parks still perform reasonably well. Heat, humidity, and early monsoon showers reduce wildlife activity, especially in the afternoons.
Good Conditions
- Wilpattu — Less affected by early monsoon patterns; wildlife around the villus remains reliable.
- Udawalawe — Elephants still easy to see, though heat reduces activity later in the day
- Kumana — peak bird season
Decent Conditions
- Yala — Possible to have good drives, but vegetation thickens and showers reduce visibility.
- Minneriya / Kaudulla — Wildlife present but scattered; not Gathering season.
Book in Advance, but No Rush
May is warm, humid, and changeable. Seas along the south and west coasts can be rough, and some water‑based activities may be cancelled due to weather. Afternoon showers are common across the island, and early monsoon winds can affect travel plans. On the positive side, crowds thin out, prices drop, and the landscapes turn lush and green.
Most places have availability in May, especially outside the holiday periods, so you don’t need to book everything months ahead. Just secure your key stays and trains, and you’ll be fine

Verdict: Should You Visit Sri Lanka in May?
May is a mixed month to visit Sri Lanka. It’s not ideal for beaches on the south and west coasts, but the Hill Country and Cultural Triangle remain enjoyable, and the east coast begins to open up toward the end of the month. Wildlife viewing is decent but not exceptional. If you’re flexible with weather and prefer quieter travel, May can still work — just don’t expect the stable sunshine of earlier months.
