Highest temperature in London on May 31?

Highest temperature in London on May 31? is a weather prediction market focused on the maximum temperature recorded at London City Airport Station on 31 May 2026. The market will resolve to the temperature range containing the day’s highest observed reading in degrees Celsius, using Wunderground as the official source. Because the resolution source reports temperatures in whole degrees Celsius, traders are forecasting a range rather than an exact decimal value. The event is active from May 29 through May 31, 2026, and it cannot resolve until the first data point for June 1 is published, allowing late revisions within the stated timeframe to be considered. Current market probability sits at about 15%, suggesting traders see a relatively low chance of a hotter outcome. As a recurring London weather event, this prediction market reflects broader market sentiment around daily temperature expectations, local weather conditions, and the odds of a warmer-than-usual late-May reading in London.
