Paris typically experiences mild spring temperatures in mid-April, with historical averages around 16°C. The market question focuses on whether the city's highest temperature on April 18 will reach 23°C or higher, representing a notably warm day for this time of year. The YES side is currently priced at just 5%, indicating the market expects cooler conditions than the 23°C threshold. This low probability reflects typical April weather patterns, where temperatures often fluctuate between 12–18°C. The market resolves based on the official maximum temperature recorded by meteorological authorities in Paris for that specific date. A 23°C high would represent above-average warmth, potentially driven by southerly air masses or unusually sunny conditions. The 5% odds pricing suggests strong consensus that such warmth is unlikely given seasonal norms and current weather forecasts. Traders monitoring this market would be watching early-week weather patterns, high-pressure systems, and any unexpected warming trends. The market has recorded $4,070 in 24-hour volume with $1,504 in available liquidity, indicating modest but active interest in temperature predictions for this period. April temperature markets are particularly sensitive to shifting weather patterns, which can quickly change odds as forecasts update. This daily temperature market represents a straightforward, easily-verifiable resolution criterion tied to publicly available meteorological data.
