August 2026 is reported as the world’s joint-hottest month on record, with global temperatures measured at about 1.65°C above pre-industrial levels. Scientists citing the EU’s Copernicus Climate Change Service say August matched the previous all-time record set by July 2023.
The reporting links the extreme heat to an ongoing period of exceptionally warm conditions that began earlier in the year, with heatwaves continuing from May. Several outlets also note very high sea-surface temperatures for August. Coverage highlights that the El Niño system is developing and is expected to strengthen further, which could contribute to additional warming in coming months.
While outlets broadly agree on the record temperature figures and the “joint hottest month” finding, they vary in emphasis: some focus on the specific month-by-month record, others on broader seasonal context or on how close the world is to the 1.5°C threshold referenced in climate agreements. Overall, the consensus is that August reinforces a longer-term trend of rising global heat.
