The ongoing El Niño phenomenon is expected to reduce rainfall in Sri Lanka in the coming months, according to Director General of the Department of Meteorology, Ajith Wijemanna.
Speaking at a special media briefing held at the Department of Government Information on July 6, Wijemanna said El Niño affects countries differently, bringing heavy rainfall to some regions while causing severe drought conditions in others.
He noted that the current El Niño condition remains at a weak level but could influence Sri Lanka’s seasonal weather patterns. According to the Meteorology Department, rainfall during the southwest monsoon season is likely to decrease, with relatively dry weather expected towards the end of July and throughout August. However, some areas may still experience heavy rainfall exceeding 250 mm.
Wijemanna further stated that disturbances in the Pacific Ocean could bring some rainfall during September. He also pointed out that Sri Lanka may experience below-average rainfall during the early part of next year.
Referring to historical data, he said Sri Lanka has experienced around 28 El Niño events over the past 75 years, including nine particularly strong episodes. Studies show that these stronger El Niño events were associated with increased rainfall during October.
Citing data released by the World Meteorological Organization on July 5, Wijemanna said the current El Niño is developing rapidly and could become stronger than previous events.
