What May is like in Sri Lanka

May is humid, with highs near 88F (31C), as the southwest monsoon arrives and brings rain to the west and south coasts. The east coast season starts, with calmer seas and drier days around Trincomalee and Pasikudah. Crowds and prices drop. Vesak, on the full moon of May, fills the country with lanterns and lit displays.

It is a mixed month. It suits travelers who plan around the monsoon and head east for beaches. The Cultural Triangle is still workable. Families should avoid swimming on the southwest coast, where seas get rough. If you want the south coast at its best, come from December to April.

Make the most of May

What is especially good about Sri Lanka this month.

02

What to pack for May

Our timing tip

Check the Vesak full moon date and plan an evening in Colombo or Kandy to see the lanterns, but expect bars and many shops to be closed.

Things to do in Sri Lanka

Beat the crowds

  • Follow the monsoons, not the calendar. In July and August, when Europe's summer holidays fill Galle and Ella, spend more of your time on the dry east coast.
  • Climb Sigiriya at opening or in the last two hours, and consider the Pidurangala rock next door for the view of Sigiriya itself.
  • If the hill country train is running on your dates, book reserved seats as far ahead as allowed. Unreserved carriages in peak season are standing room only.
  • Avoid full moon (Poya) weekends at pilgrimage sites like Adam's Peak and Anuradhapura, when they are packed with pilgrims.

Know before you go

  • Every full moon (Poya) day is a public holiday. Alcohol sales are banned, and some shops and restaurants close.
  • Sinhala and Tamil New Year in mid April closes many businesses for several days. Plan transport and meals ahead.
  • Yala National Park often closes its main zone for part of the dry period, roughly September to mid October, to let the park recover.
  • Rough seas during the southwest monsoon (May to September) close many beaches on the south and west coasts to swimming and stop some whale-watching boats.
