Sri Lanka weather warnings July–October 2026

Overview

Throughout August and September 2026, Sri Lanka experienced volatile weather characterized by high heat, heavy rainfall, and hazardous maritime conditions. In late August, increased temperatures were noted in the Eastern Province and several northern districts, alongside forecasts for heavy rainfall exceeding 75 mm in the Sabaragamuwa and Western Provinces. An amber advisory was issued in late August for rough seas, with wave heights reaching up to 2.5 meters.

By early September, an amber-level lightning advisory was issued for the Eastern and Uva provinces due to dangerous electrical activity. Heavy rainfall continued, with accumulations reaching 100 mm in some locations by mid-September, raising concerns regarding flash flooding and hazardous road conditions.

In late September, weather warnings intensified. On 20 September, the Department of Meteorology forecast rainfall exceeding 100 mm for parts of the Sabaragamuwa and Central provinces, specifically Kandy and Nuwara Eliya. An amber advisory for heavy rainfall was issued for ten districts across the Western, Sabaragamuwa, and North Western provinces, citing potential danger to lives and property. By 29 September, heavy rainfall exceeding 50 mm was expected across the Uva, Eastern, and Central provinces.

In October, a new low-pressure area developed near Sri Lanka, triggering further warnings for heavy rainfall exceeding 100 mm in parts of the Sabaragamuwa and North Western provinces, as well as intermittent thunderstorms in the Central and Southern regions.
