Highest temperature in Paris on May 31?

Highest temperature in Paris on May 31? is a weather prediction market asking traders to forecast the highest temperature recorded at Paris-Le Bourget Airport on 31 May 2026. The market resolves to the temperature range containing the day’s maximum reading, using Wunderground as the source and whole-degree Celsius measurements for settlement. Because the outcome depends on the final published data for that date, it cannot resolve until the next day’s first data point appears on the resolution source. This event matters for participants tracking Paris weather, France climate conditions, and short-term temperature expectations in a recurring daily temperature market. Current market probability is about 10%, indicating relatively low odds for the listed outcome category, though market sentiment can change as weather forecasts update. The forecast is focused on the single highest observed temperature rather than an average, low, or overnight reading, making timing and source verification especially important for event prediction.
