Official Met Office observations from key London stations, including Heathrow and London City Airport—the market's resolution source via Wunderground—confirm a maximum temperature of 24°C on May 1, 2026, under partly cloudy skies with light winds, solidifying trader consensus at 100% implied probability for this outcome. This aligns with pre-event forecast model consensus from the UK Met Office, projecting highs near 24°C amid a high-pressure ridge and southerly airflow, warmer than the typical May average of 16–18°C but within climatological norms. Scenarios that could challenge resolution include rare post-finalization data revisions for sensor anomalies or a overlooked higher reading from a qualifying station, though quality-controlled observations reduce this risk as data stabilizes within 24–48 hours.

This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 1 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.
