Sri Lanka is expected to experience unsettled weather conditions on 31 May 2026,
with showers, thunderstorms, strong winds, and rough sea conditions affecting several
parts of the country. The southwest monsoon continues to influence weather patterns,
bringing significant rainfall to many regions.

According to the latest forecast, showers or thundershowers will occur at times 
in the Western, Sabaragamuwa, and North-Western provinces, as well as in the districts
of Galle, Matara, Kandy, and Nuwara Eliya. Residents in these areas should be prepared
for frequent rain throughout the day. Fairly heavy rainfall exceeding 50 mm is likely
at some locations in the Western and Sabaragamuwa provinces and in the Galle and
Matara districts, increasing the risk of localized flooding in low-lying areas.

Meanwhile, a few afternoon or evening showers may also occur in the Uva Province
and in the Ampara and Batticaloa districts. Most other areas are expected to experience
comparatively less rainfall.

Strong winds will be another key feature of the day’s weather. Wind speeds of 30
to 40 kmph are expected at times over the western slopes of the central hills, the
Northern, North-Central, North-Western, and Southern provinces, as well as in the
Trincomalee district. People are advised to take precautions against possible damage
from falling branches, temporary structures, and lightning associated with thunderstorms.

### Rough Seas and Marine Warning

Weather conditions at sea are expected to be challenging. Showers or thundershowers
may occur in sea areas stretching from Puttalam to Hambantota via Colombo and Galle.
Southwesterly winds are forecast to strengthen significantly, reaching 60 to 65 
kmph at times in the sea areas from Mullaittivu to Chilaw via Kankasanthurai and
Mannar, and from Galle to Pottuvil via Hambantota.

These sea areas are expected to be very rough, while other surrounding waters will
remain fairly rough. Wave heights may increase to between 2.0 and 2.5 meters along
parts of the western and southern coastal waters. Fishermen, naval operators, and
maritime communities are advised to exercise extreme caution and closely monitor
weather updates before venturing out to sea.
