The summer of 2026 had the hottest summer months on record in Europe.

Omissions

• Copernicus states that summer 2026 (June–August) was the third warmest on record for Europe as a whole, behind 2024 and 2022 — not the hottest — so the superlative 'hottest' is not correct for the entire European continent.
• The 'warmest on record' record applies specifically to western Europe, a sub-region of the continent that is narrower than the European Union.
• At global level the June–August 2026 period was the joint warmest on record, on par with 2024, which supports a 'hottest on record' framing only when the scope is global rather than European.
• June 2026 was the hottest June on record for western Europe but only the second warmest June globally; July 2026 ranked only 11th warmest for European land, showing the 'hottest summer' framing relies on selecting the most favourable regional metric.
