This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 11 Jul '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.Latest Met Office guidance points to a 30°C maximum in London on July 11 amid an established heatwave driven by a strong high-pressure system promoting clear skies, light winds, and strong insolation. Ensemble forecasts from ECMWF and GFS show modest spread around this value due to uncertainties in boundary-layer mixing and urban heat-island amplification, which can add 1–2°C in central districts. With the heatwave already delivering 32–34°C peaks earlier in the week, traders weigh the risk of slight cooling from increasing high cloud against continued southerly flow. Resolution hinges on the official Met Office daily maximum recorded at standard sites; model updates over the next 48 hours will refine the precise outcome between 28–31°C.
