Are the southern Sri Lankan beaches safe to swim in May?

No, swimming on the southern beaches of Sri Lanka is generally not safe in May. This month is when the southwest monsoon begins, and it brings choppy water, big surf, and dangerous rip currents.

In May, the sea along the southern shoreline, including places people love like Mirissa and Unawatuna, becomes really unstable, with powerful undercurrents running beneath you. If you’re hoping for calmer, safer water during May, you will need to go toward the east coast beaches. Examples include Trincomalee, Nilaveli, or Arugam Bay, because those areas hit their drier and calmer stretch during this period.
