Ensemble forecasts from the Met Office and ECMWF place London’s maximum temperature on May 18 near 14–16 °C under the influence of a broad Atlantic low-pressure system driving scattered showers and moderate westerly winds. These conditions reduce daytime solar insolation while promoting turbulent mixing in the boundary layer, which caps surface warming and keeps the daily high tightly clustered around the seasonal average. Small variations in shower timing, cloud thickness, or slight wind shifts can easily alter the peak by 1–2 °C, accounting for the closely matched market probabilities on the 14 °C, 15 °C, and 16 °C outcomes. The next official model runs will further constrain the range ahead of official station observations.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the London City Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
