April 20, 2026 marks another opportunity to trade weather-specific outcomes in London's prediction market. This market focuses on a precise outcome: whether the city's highest temperature will be exactly 16 degrees Celsius. London typically experiences mild spring temperatures in late April, with daily highs ranging between 12 and 18 degrees Celsius depending on prevailing weather systems. A high of exactly 16°C falls within this normal range—neither particularly cold nor warm for the season. The 3% odds currently reflected in the market suggest traders view this exact temperature outcome as unlikely, though this may shift as April 20 approaches and weather forecasts become more certain. Market resolution depends on official UK Met Office temperature data for London. Such specific daily temperature markets allow participants to express detailed weather forecasts or manage weather-dependent business interests. The market closes at midnight UTC on April 21, 2026, with settlement determined by the maximum temperature recorded during April 20 in London.
