Recent Met Office forecasts point to a daytime maximum near 27°C across London on May 22 under building high pressure that promotes clear skies and strong solar heating. This setup, with light winds and limited cloud cover, favors efficient surface warming above the seasonal average of 18–20°C while introducing minor uncertainty around peak boundary-layer mixing and any residual moisture. Traders assign the highest implied probability to 27°C, followed closely by 28°C, reflecting tight clustering in ensemble guidance between these thresholds. Small shifts in wind direction or insolation could easily move the verified reading at London City Airport into adjacent bins, and updated model runs later today will likely refine the outlook ahead of official verification.

This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 22 May '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the London City Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/gb/london/EGLC.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Recent Met Office forecasts point to a daytime maximum near 27°C across London on May 22 under building high pressure that promotes clear skies and strong solar heating.
