This weather prediction market tracks whether London will reach a maximum temperature of exactly 12°C on April 18, 2026. Daily temperature markets resolve using official UK Met Office data, which provides reliable hourly and maximum temperature readings. The current market shows 0% odds on YES, suggesting traders believe the actual high will differ from 12°C. In April, London typically experiences temperatures ranging from 8°C to 15°C, so 12°C sits near the middle of historical spring patterns. A reading of exactly 12°C is notably specific—precision weather markets often see low probability outcomes as traders account for the narrow range. The market ends at midnight UTC on April 18, when the official Met Office maximum temperature for the day resolves the outcome. Early odds of 0% reflect trader conviction that the temperature will be different, or limited initial participation. As the event date approaches, odds may shift based on weather forecasts and observed conditions throughout the day.
