Sri Lanka Braces for Enhanced Monsoonal Showers and Rough Seas Amid Active Southwest Monsoon

Colombo, Sri Lanka – May 27, 2025 — Sri Lanka is experiencing intensified weather conditions due to the active southwest monsoon, with heavy rains, strong winds, and rough seas expected to persist over the coming days, according to the country’s Department of Meteorology.

Showers and thunderstorms are forecast for the Western, Sabaragamuwa, and North-Western provinces, as well as in the districts of Nuwara-Eliya, Kandy, Galle, and Matara. Rainfall in some areas is expected to exceed 100 mm, potentially leading to localized flooding and disruptions.

Other regions across the island may also experience occasional showers.

Strong winds ranging between 40 to 50 km/h are likely in the western slopes of the central hills, Northern, North-Central, and North-Western provinces, along with the districts of Hambantota and Trincomalee. The public is urged to exercise caution during thunderstorms, particularly in areas prone to lightning and sudden gusts of wind.

Marine Warnings Issued

The Department of Meteorology has also issued advisories for seafarers and fishing communities. Sea areas off the coast from Chilaw to Kankasanthurai via Puttalam and Mannar, and from Galle to Pottuvil via Hambantota, are expected to be very rough, with wind gusts reaching 60–70 km/h. Naval and fishing vessels have been strongly advised not to venture into these waters until further notice.

Other coastal regions, including areas from Chilaw to Galle via Colombo and from Kankasanthurai to Trincomalee via Mullaitivu, may also experience wind speeds of 50–60 km/h. Wave heights in affected zones could rise between 2.5 to 3.0 meters, with the potential for dangerous swell waves and surges along the shorelines.

Authorities urge all communities, especially those in low-lying and coastal areas, to remain alert and follow future updates from the Department of Meteorology.
