Several spells of showers are expected across parts of Sri Lanka on 16 June 2026, according to the latest weather forecast issued by the Department of Meteorology. Rainfall activity will mainly affect the Western, Sabaragamuwa and North-Western provinces, along with the districts of Galle, Matara, Kandy and Nuwara Eliya.
Residents in these areas can expect intermittent showers throughout the day. Meanwhile, showers or thundershowers may develop at a few locations in the Uva and Eastern provinces and in the Mullaittivu district after 2.00 p.m. Due to the possibility of thunderstorms, the public is advised to remain alert and take precautions against lightning and temporary localized strong winds.
Fairly strong winds with speeds of 30–40 kmph are also expected at times over the western slopes of the central hills, the Southern and North-Central provinces, and the Trincomalee district. These windy conditions may cause minor disruptions, particularly in exposed areas.
Sea Area Forecast
Showers or thundershowers are expected in several sea areas extending from Chilaw to Matara via Colombo and Galle during the next 24 hours. Winds over the surrounding sea areas will be south-westerly with speeds ranging between 30–40 kmph.
Wind speeds may increase up to 50–60 kmph at times in the sea areas from Galle to Pottuvil via Hambantota. In addition, winds can reach up to 50 kmph in sea areas extending from Trincomalee to Galle via Kankasanthurai, Puttalam and Colombo.
Sea conditions will be rough at times off the coast from Galle to Pottuvil via Hambantota, while seas from Trincomalee to Galle via Kankasanthurai, Puttalam and Colombo will be fairly rough. Wave heights are expected to increase to around 2.0–2.5 metres in sea areas from Colombo to Pottuvil via Galle and Hambantota.
Fishermen and naval communities are advised to exercise caution, as strong gusty winds and very rough seas can occur during thundershowers.
