This market will resolve to the temperature range that contains the highest temperature recorded at the London City Airport Station in degrees Celsius on 28 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.Latest Met Office guidance points to a 26°C maximum in London on June 28 as the most probable outcome, following the recent extreme heatwave that peaked mid-week with widespread 35–38°C readings. A shift toward cooler Atlantic air and increased cloud cover is expected to moderate temperatures over the weekend, aligning with ensemble model consensus that places the highest likelihood near 25–27°C. Historical June averages hover around 20–22°C, underscoring the lingering warmth, yet forecasters note typical uncertainties from local urban heat islands and small shifts in steering patterns could nudge the peak slightly higher or lower. Upcoming model updates and official briefings this weekend will provide the key data releases influencing final trader positioning.
