The southwestern coast, including Colombo, Galle, and Bentota, bears the brunt of the southwest monsoon in June.

These rains make the region’s beaches less ideal for swimming and sunbathing due to choppy waters and occasional red-flag warnings.

- Sunshine: Limited, with cloudy skies prevailing, though there may be some breaks of sun
2. Eastern Sri Lanka: Trincomalee, Batticaloa, and Arugam Bay
On the east coast, the climate is drier, making June an ideal month for beach activities, snorkeling, and surfing.

Crowds and Costs in Sri Lanka in June
With the arrival of the monsoon season, June is part of Sri Lanka’s low tourist season, resulting in reduced crowds and more affordable travel options. Popular destinations in the southwest, like Colombo, Galle, and Bentota, see fewer visitors, which can make for a peaceful experience despite the occasional rain. Hotels, activities, and transportation tend to offer off-peak rates, allowing travelers to save on accommodations and experiences that might otherwise be more expensive during peak season.
However, the east coast experiences higher demand, especially in areas like Arugam Bay, as tourists flock to the dry, sunny beaches. While these areas see more visitors than the southwest, they’re still far less crowded than during peak months, offering a balance between affordability and favorable weather.
Festivals in Sri Lanka in June
Two major festivals are celebrated in Sri Lanka in June—Eid al-Fitr by the Muslims, and Poson Paya, a Buddhist festival. Poson Poya marks an immensely crucial occasion for Buddhism in Sri Lanka—the advent of Buddhism to the country by Mahinda, a Buddhist monk and the son of the Indian emperor Ashoka. As the most sacred Poya (full moon day) of the year, festivities are in full swing at all corners of the country, but Anuradhapura and Mihintale receive the highest number of pilgrims.
For those looking to experience Sri Lanka’s natural beauty without the usual crowds, June can be a rewarding time to visit. The weather in Sri Lanka in June offers a contrast between the rainy southwest and the sunny, dry east, providing options for travelers with varied interests. Whether you’re drawn to the vibrant cultural celebrations, the tranquil highlands, or the beaches of Trincomalee, Sri Lanka in June promises an affordable and unique adventure in a truly captivating landscape.
