Paris weather predictions for April 18, 2026 are determined by meteorological forecasts and actual recorded data. This market resolves based on the highest temperature recorded in Paris during April 18, from 00:00 to 23:59 local time. The 0% YES odds indicate that market participants currently assess the probability of the maximum temperature being exactly 14°C as extremely low, reflecting confidence that the actual high will differ from this specific threshold. April in Paris typically ranges from 8°C to 16°C, placing 14°C well within the normal spring temperature range. However, the market's pricing suggests traders expect the day's maximum to lie outside this exact value—either warmer or cooler. Temperature markets rely on official meteorological data from Meteo-France, ensuring outcomes are objective and verifiable. Resolution occurs within 24-48 hours after April 18 concludes, based on recorded temperature data. As the forecast date approaches, odds may shift significantly as meteorological models become more precise and consensus emerges around the expected daily high.
