This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 18 Jun '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the London City Airport Station, 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 until the first data point for the following date has been published on the resolution source. 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.High pressure building across southern England is driving trader sentiment toward a peak of 27–29°C on June 18, with BBC Weather and Met Office guidance currently forecasting sunny intervals and a high of 28°C under light south-westerly flow. This setup favors clear skies and daytime warming above the June climatological average of roughly 20°C, though modest uncertainty remains from possible variable cloud or a slightly stronger breeze that could cap readings near 27°C or allow brief pushes toward 29°C. Model consensus supports these thresholds as the resolution window narrows, with traders weighting the latest official guidance most heavily.
