This market tracks whether the highest temperature recorded in Paris on April 20, 2026, will be exactly 13°C. Paris's springtime weather is highly variable, with April temperatures typically ranging between 8–18°C depending on prevailing weather patterns and pressure systems. The market requires exact precision—13°C, not 12 or 14—which explains the narrow distribution. The 1% YES odds suggest traders view this specific outcome as highly unlikely, reflecting the inherent difficulty in predicting weather to the nearest degree. While 13°C is meteorologically plausible for Paris in late April, hitting that exact point requires a particular balance of atmospheric conditions. Historical April data for Paris shows typical highs cluster around 12–16°C, so 13°C sits within the probable range but must coincide with unique daily weather conditions. Prediction markets price specific temperature points much lower than broader forecasts because the outcome space is discrete—many potential outcomes exist between 8 and 18 degrees. Resolution will use the official daily high temperature reported by Météo-France or equivalent meteorological authority for the Paris region. The stable low odds suggest limited trader conviction that 13°C will materialize, with few revisions as the event date approaches.
