# Will summer 2026 be the UK's hottest summer on record?

Settled · $1,724 traded · listed on Polymarket

## Result

**Yes** won. Settled 2026-10-03.

## About

This market will resolve to "Yes" if the Met Office's mean temperature for the United Kingdom for meteorological summer 2026 (June 1 to August 31, 2026) is the highest for any summer in the Met Office record. Otherwise, this market will resolve to "No".

The current UK summer mean temperature record is 16.12°C, set in summer 2025. A UK summer 2026 mean temperature greater than 16.12°C is necessary and sufficient for a "Yes" resolution; a value equal to or below 16.12°C resolves "No".

The primary resolution source will be the figure in the "sum" (summer) column of the row for year "2026" in the Met Office UK mean air temperature series (https://www.metoffice.gov.uk/pub/data/weather/uk/climate/datasets/Tmean/date/UK.txt). The market will resolve on the first value the Met Office publishes for summer 2026 in this series and will not be affected by any subsequent revision.

If the Met Office renders this series permanently unavailable, other official Met Office data for the UK summer 2026 mean temperature may be used. If no figure for summer 2026 has been published by the Met Office by September 30, 2026, 11:59 PM ET, this market will resolve based on a consensus of credible reporting.
