Ocean Temperatures Hit Record High Amid El Niño Concerns
Ocean temperatures have reached record highs, according to Copernicus Climate Change Service (C3S). The average surface temperature in August 2026 was 21.1°C (70°F), exceeding the previous maximum of 21.09°C set in March 2024. Experts warn that this record-breaking temperature, typically reached in March-April, is unusual and could have severe consequences for marine ecosystems and coastal populations. The El Niño phenomenon, which adds heat to the already warming oceans, is expected to peak between November 2026 and January 2027.2 sourcesSee all sources
