Official Met Office observations from London Heathrow and nearby stations confirm the minimum temperature reached 14°C overnight into May 3, 2026, driving trader consensus to a 100% implied probability on this outcome. Mild southwesterly winds around 7-8 knots and patchy cloud cover limited radiative cooling, while the urban heat island effect in Greater London prevented sharper drops typical of clear spring nights. This aligns with climatological May norms of 8-10°C lows at Heathrow but reflects the specific synoptic pattern of high pressure influence over southern England. Final quality-controlled data release could theoretically revise readings if an anomalous rural probe emerges, though current site reports show no discrepancies.

This market will resolve to the temperature range that contains the lowest temperature recorded at the London City Airport Station in degrees Celsius on 3 May '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.Official Met Office observations from London Heathrow and nearby stations confirm the minimum temperature reached 14°C overnight into May 3, 2026, driving trader consensus to a 100% implied probability on this outcome.
