A cyclone slams into south-eastern India. An estimated 300,000 deaths resulted from the disaster.

On 25 November 1839, the port city of Coringa in present-day Andhra Pradesh on the southeastern coast of British India was battered by a tropical cyclone that destroyed the harbour. Known as the 1839 Coringa cyclone and sometimes also referred to as the 1839 India cyclone and 1839 Andhra Pradesh cyclone, its storm surge caused wide damage. It killed over 300,000 people, making it the second-deadliest storm worldwide after the 1970 Bhola cyclone. Many ships were destroyed and houses were washed out by rising rivers and streams. Croplands were inundated and many animals drowned due to the floods and storm surge.

November 25 is the 329th day of the year in the Gregorian calendar; 36 days remain until the end of the year.
