This market will resolve to the temperature range that contains the lowest temperature recorded at the London City Airport Station in degrees Celsius on 17 Aug '26. The resolution source for this market will be information from Wunderground, specifically the lowest 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.
Forecast models from the Met Office and BBC Weather show the August 17 overnight low in London hovering between 18°C and 19°C, creating the tight market split between those two outcomes. Clear skies and light winds expected under high pressure favor strong nocturnal radiative cooling, while any increase in cloud cover or urban heat retention could hold temperatures near the higher end of that range. Ensemble guidance and short-range updates remain the key variables traders are watching ahead of final resolution, with historical August minima in the mid-teens providing context but little direct guidance for this specific night.
