August 2026 Confirmed as Hottest Month Ever Recorded Globally

August 2026 set a new global temperature record, exceeding all previous months and marking the most extreme heat in recorded history.

By Nadia Hussain · First published 10 Sept 2026

In brief

  1. August 2026 was confirmed as the hottest month ever recorded globally, with temperatures 1.65 degrees Celsius above pre-industrial levels.
  2. The global average temperature from September 2025 to August 2026 was 1.48 degrees Celsius higher than the 1850-1900 baseline.
  3. Western Europe experienced its hottest summer on record, surpassing the previous extreme heat event in 2003.
  4. Ocean surface temperatures reached unprecedented highs in August, intensifying heatwaves and climate-related disasters worldwide.
  5. Scientists attribute the record heat mainly to human-caused climate change and a strong El Niño, warning of worsening risks without major action.

Update 10 Sept 2026, 5:11 pm UTC

Recent coverage confirms August 2026 as the hottest month ever recorded globally, with multiple outlets highlighting the role of a strong El Niño and human-driven climate change. Reports also emphasize record ocean temperatures and unprecedented extreme weather events across continents.

Update 10 Sept 2026, 9:40 am UTC

Recent coverage highlights that August 2026 has surpassed all previous records as the hottest month ever globally, with Western Europe experiencing its warmest summer since records began. The Copernicus Climate Change Service also confirmed that the 12-month period ending in August 2026 saw a record global temperature anomaly.

Update 10 Sept 2026, 6:40 am UTC

New data from the EU's Copernicus climate monitor confirms August 2026 was the single hottest month ever recorded globally, surpassing previous records. Ocean temperatures also reached unprecedented levels, and scientists now say these conditions are the most extreme in at least 100,000 years.

How it started

Concerns over rising global temperatures have steadily grown in recent years, with scientists closely monitoring monthly heat records. By mid-2026, the planet was already experiencing unusual heat, partly due to a strong El Niño event amplifying the effects of ongoing climate change.

Researchers and climate agencies worldwide tracked temperature data through the summer, comparing it with previous record months, especially July 2023, which had set the previous global high.

How it unfolded

In early September 2026, scientists confirmed that August had tied with July 2023 as the hottest month ever recorded globally, with average temperatures reaching 1.65 degrees Celsius above pre-industrial levels. Reports from European climate agencies, including the EU's Copernicus service, provided detailed data supporting these findings.

The EU climate monitor announced that August was the hottest single month ever recorded, and noted that the summer of 2026 was the warmest yet measured in western Europe. Other international agencies echoed these findings, with experts highlighting the dual influence of human-caused climate change and the ongoing super El Niño.

Media coverage in the US, UK, and Europe emphasized the immediate impacts of this heat, from health risks to disruptions in agriculture and ecosystems. Scientists warned that these conditions could lead to more frequent and severe extreme weather events. They also pointed to the risk that global temperature records may continue to fall if current trends persist.

Where it stands

With August 2026 now confirmed as a joint record-holder for global heat, the scientific consensus is clear: the world is experiencing unprecedented warming. The combination of a strong El Niño and long-term climate change has pushed global temperatures to new highs.

Communities and governments are now facing mounting pressure to adapt to these new realities and consider stronger measures to address the causes and consequences of climate change.

What to watch

Scientists caution that the coming months could see even more temperature records broken if current patterns persist. Policymakers and climate agencies are expected to monitor ongoing weather trends closely, while the public and private sectors may need to brace for further disruptions from extreme heat and related weather events.
