This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 19 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 16°C as London's highest temperature on March 19, driven by converged ensemble forecasts from the Met Office and ECMWF models, which project daytime maxima of 15-16°C amid a mild Atlantic ridge pattern with partly cloudy skies and light southerly breezes. Supporting evidence includes recent soundings from Heathrow showing stable boundary layers capping warmth, aligning with historical March climatology where averages hover around 11°C but current sea surface temperature anomalies enable this uptick. Realistic challenges include an unforeseen breakdown in the upstream high-pressure ridge allowing a warmer continental airflow, potentially lifting peaks to 17°C+, though model spreads indicate under 5% odds for such divergence ahead of verification.",
