In 2025, Lake Tanganyika recorded water levels and surface temperatures significantly above normal, according to a report by the World Meteorological Organization (WMO). The lake’s level was classified as 'very above normal,' reaching or exceeding the 90th percentile of the 1995-2020 historical series. Surface temperatures were very higher than normal in January and July 2025, with variations among African lakes, including Victoria and Malawi.
