This market predicts whether Paris will experience a maximum temperature of exactly 11°C on April 20, 2026. Weather forecasting at the single-degree level is exceptionally specific and precise. Daily temperature highs in Paris during late April typically range from 12°C to 16°C, depending on atmospheric pressure systems and seasonal weather patterns. The current 0% YES odds reflect market participants' collective assessment that hitting exactly 11°C is unlikely, though cooler-than-normal conditions remain physically possible. For resolution YES, the official high temperature recorded by Météo-France must be exactly 11°C—not 11.1°C or 10.9°C. Current pricing implies traders view significantly colder-than-typical conditions as improbable for April 20. The $870 24-hour trading volume indicates limited activity, typical for highly specific weather outcomes. This market closes at midnight UTC on April 20. Weather prediction markets attract traders analyzing jet-stream patterns, seasonal trends, and high-pressure system forecasts rather than long-term climate shifts. The outcome hinges entirely on official meteorological data from France's national weather service.
