Copernicus said Western Europe posted its hottest June-July average on record in 2026.
Why it matters: The record points to rising heat risk for power systems, transport, agriculture and public health across major European economies. It also highlights how prolonged heat can deepen drought conditions and strain business continuity planning.
- Copernicus said Western Europe's June-July 2026 average temperature reached 21.62°C, topping the previous June-July record from 2022.
- June 2026 was Western Europe's hottest June on record at 20.74°C, or 3.05°C above the 1991-2020 June average.
- Copernicus said an unusually early late-May heat wave was followed by heat through June and another wave in early July.
- AP said the summer heat fueled wildfires, drought stress and projected heat-related deaths across the region.
Western Europe set a new average-temperature record for June-July 2026, with Copernicus saying the two-month average reached 21.62°C and surpassed the prior record from 2022 Copernicus.
The record followed a very hot June. Copernicus said June 2026 was Western Europe's hottest June on record at 20.74°C, 3.05°C above the 1991-2020 June average WMO.
The heat began unusually early, with a late-May event that carried into June and was followed by another heat wave in early July Copernicus. Copernicus said persistent high-pressure systems trapped heat over western Europe and that dry soils reduced natural cooling Copernicus.
The operational toll is already visible. AP reported wildfires, drought stress and projected heat-related deaths across the region, while Copernicus said June brought widespread dryness across western and central Europe WMO.
Copernicus's June assessment also shows how quickly the season escalated: the late-May heat wave was followed by record June heat, then another wave in early July Copernicus. The record is a sign of repeated seasonal heat extremes, not a single-day temperature spike.
By the numbers
- 21.62°C - Western Europe's June-July 2026 average temperature, according to Copernicus.
- 20.74°C - Western Europe's June 2026 average temperature, its hottest June on record.
- 3.05°C - How far June 2026 sat above the 1991-2020 June average.
Yes, but: The headline record is for the June-July average temperature across Western Europe, not an absolute single-day heat record.
What's next: Copernicus said another heat wave emerged in early July, so more summer temperature updates are likely as the season continues.
