Trader consensus on Polymarket reflects tight uncertainty in UK Met Office and ECMWF ensemble forecasts for London's highest temperature on March 27, with models clustering around 12–13°C amid a weak Atlantic front bringing cloudy skies and light winds. Recent 48-hour updates from GFS and UKMO runs indicate a slight cooling trend due to increased northerly airflow and persistent low cloud cover suppressing daytime heating, nudging the peak toward 12°C (47.5% implied probability) over 13°C (44.0%), though minor timing shifts in the front could allow brief clearer intervals for a 13°C reading. Historical late-March averages hover near 12°C, and new 12Z model outputs expected soon may refine this razor-thin split before resolution based on official Heathrow observations.

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.
