World's Oceans Record Hottest June in 2026
Multiple outlets reported that June 2026 was the warmest month on record for the global oceans, with average sea‑surface temperatures surpassing previous highs and a potentially powerful El Niño expected to add further heat.
The world's oceans recorded their hottest June on record in 2026, according to several news outlets.
Global average sea‑surface temperature for June 2026 was reported as 20.98 °C by Indian and other sources, while social and western outlets reported the figure as 21 °C.
June 2026 ocean temperatures exceeded the previous records set in 2023 and 2024.
A potentially powerful El Niño could boost global heat in the oceans and atmosphere further in 2026 and into next year, as noted by multiple sources.
The record June ocean temperature was logged by Copernicus, the EU's Earth‑observation programme (France 24). EU monitors said the first half of 2026 was marked by sustained and exceptional ocean warmth (Al Jazeera). France 24 also reported that the oceans have never been warmer. Tass reported that June 2026 temperatures in Western Europe broke the record as the hottest in history. Mother Jones noted that on June 21, temperatures outside the polar regions exceeded extraordinary highs observed in 2023 and 2024. Bluesky reported that extra thermal energy from the ocean heat directly fuels more intense storms, floods and droughts.
