This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 20 Mar '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.

"context_description": "Trader consensus overwhelmingly favors a highest temperature of 14°C in London on March 20, driven by the UK Met Office's latest ensemble forecasts showing a daytime maximum of 13-14°C under partly cloudy skies with light winds from the northwest. This aligns with historical March norms at Heathrow (averaging 11-13°C) and current ECMWF model runs projecting stable high-pressure influence limiting warming. Supporting evidence includes verified GFS and UKV model outputs converging on 14°C peaks around 2-4 PM GMT, with low humidity curbing any heat buildup. Realistic challenges include an unforeseen southerly airflow shift introducing mild Atlantic air, potentially pushing highs to 15-16°C, or prolonged cloud cover dropping it below 13°C—though current probabilities remain under 1% per model spreads.",
