Current Met Office guidance indicates a daytime maximum of 17 °C for London on May 17, with an approaching Atlantic front expected to increase cloud cover and trigger scattered light showers that limit afternoon solar heating. Mid-May climatology at Heathrow, the likely resolution site, centers on 16–17 °C highs, so trader consensus clusters tightly around 15 °C and 16 °C because small variations in cloud thickness or frontal timing could trim peak temperatures by 1–2 °C. Ensemble model runs show modest spread in boundary-layer moisture and wind direction, creating genuine uncertainty within the narrow historical range. Updated 06Z and 12Z guidance on Saturday will refine insolation forecasts and likely shift implied probabilities ahead of resolution.

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.
