Highest temperature in Paris on July 5?

Platform comparison

Market context

A powerful heatwave is set to strike France in early July 2026, with meteorologists forecasting dangerous temperatures across the country that could push Paris daily highs into the 35–38°C range, while southern regions may reach 41°C. This intense weather event, expected to persist for 7 to 10 days, creates a volatile backdrop for the prediction market on the highest temperature recorded at Paris-Le Bourget Airport on 5 July, where the current crowd-implied probability for a 30°C peak sits at 0% despite some models suggesting a modal peak near 29–31°C.

Historical precedents from the 2026 European heatwaves, including a record 41°C in Mostar on 28 June and Paris hitting 42.6°C earlier in the week, frame the current 0% probability as a likely mispricing, given that recent data shows Paris temperatures consistently exceeding 30°C during this period. Traders should closely monitor the next updates from Météo-France and ECMWF, as the market remains highly sensitive to these forecasts with only two days until resolution, and watch for any official red heat-wave alerts issued for the 54 departments currently under warning, which could further confirm the likelihood of temperatures well above the 30°C threshold.
