Recent forecasts from Met Office and European models indicate mostly clear skies and light winds over London on June 19, favoring moderate overnight radiative cooling after daytime highs near 25–31°C. This setup supports a minimum temperature clustered around 17–18°C at official urban stations, where the urban heat island effect and measurement timing introduce small but decisive variances. Ensemble spreads reflect lingering uncertainty from subtle differences in cloud timing and boundary-layer moisture, keeping trader-implied odds tightly matched between those two outcomes while assigning lower probability to 19°C or cooler readings below 16°C. Updated model runs expected overnight will likely refine the exact minimum.

This market will resolve to the temperature range that contains the lowest temperature recorded at the London City Airport Station in degrees Celsius on 19 Jun '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.Recent forecasts from Met Office and European models indicate mostly clear skies and light winds over London on June 19, favoring moderate overnight radiative cooling after daytime highs near 25–31°C.
