August 17, Colombo (LNW): Sri Lanka may be heading towards an exceptionally hot period early next year, with temperatures potentially approaching the 40°C mark as the effects of an anticipated El Niño event become more pronounced.
Department of Meteorology climatologist Malith Fernando said the island could record unusually high temperatures by March 2027, as global temperatures are also expected to remain at elevated levels. He said Sri Lanka would not be immune to the broader warming trend and could see average temperatures climb significantly in some parts of the country.
According to Fernando, temperatures in the hottest areas could come close to 40°C, a level last recorded in Sri Lanka on April 10, 1983. The Northern, North Central and Eastern provinces, together with areas around Hambantota, are expected to be particularly vulnerable to intense heat.
Sri Lanka’s average temperature, based on long-term observations, generally falls within the 33°C to 35°C range in the warmer parts of the country. Recent readings, however, have highlighted the potential for more extreme conditions. Trincomalee recorded 39.9°C on 25 July, while several other districts also experienced temperatures well above 35°C.
Fernando noted that the heat currently being experienced across parts of the island should not necessarily be interpreted as an indication of the projected El Niño-driven conditions. The present spell of high temperatures is largely associated with the Southwest Monsoon and is considered a recurring seasonal pattern.
Polonnaruwa, Matale, Mullaitivu, Monaragala and Trincomalee have been among the areas recording particularly high daytime temperatures in recent weeks.
Meanwhile, the Meteorology Department has warned that the developing El Niño conditions could have wider consequences for Sri Lanka, including changes in rainfall patterns and an increased risk of high temperatures and drought. The Government has already established mechanisms to monitor and prepare for the potential impacts of the phenomenon.
