Highest temperature in Paris on August 3?

Platform comparison

Market context

The real-world event is the **highest temperature measured at Paris-Le Bourget Airport on 3 August**, and this market settles on the Wunderground daily history page for that station. The current crowd-implied probability of **1% YES** suggests traders are assigning only a very small chance to the specific outcome range tied to the final recorded maximum, which is plausible if the day stays materially below the hotter bands currently priced elsewhere. [2]

Recent comparable heat episodes matter because Paris has already seen exceptional summer warmth in 2026, including a severe late-June heatwave that pushed temperatures in Paris close to 41°C and set records elsewhere in France, while August climatology is usually much milder. That contrast is important for reading the market: a low implied probability does not mean the weather is benign, only that the crowd expects the day’s peak at Le Bourget to land outside the narrower settlement band more often than not. [5][8][16]

For traders, the key catalysts are the final local forecast track, any shift in the synoptic pattern, and the official station record itself, because the market resolves from the published maximum at the airport rather than a city-wide headline temperature. The practical accessibility also sits inside a regulatory frame: under Germany’s GlüStV rules, online gambling-style access can be restricted for residents; the US CFTC may assert reach over certain derivatives or event-contract activity depending on structure and venue; and “no-KYC up to $1,500” generally means a user can usually interact without full identity verification until cumulative activity crosses that threshold, which affects onboarding friction more than the market’s weather logic.
