Highest temperature in Paris on July 12?

Platform comparison

Market context

Paris-Le Bourget will record its peak temperature for 12 July 2026 by midday, with the market currently pricing any outcome above the settlement threshold at zero probability. Historical data shows July highs in Paris typically range from 20°C to 43°C, with the all-time monthly record hitting 43°C in 2019 [2]. While average July highs sit around 26°C, mid-month heatwaves have frequently pushed temperatures into the 35–37°C band, making the current 0% YES implied probability for higher ranges an outlier against recent climate patterns [2][4].

Traders should monitor the European heatwave alert schedule and daily forecasts from AccuWeather, which currently project Paris highs between 73°F and 98°F (23°C–37°C) for July 2026 [3]. A persistent red-alert heatwave across France in June 2026, which set a national record of 29.8°C as an average across 30 stations, suggests elevated baseline temperatures for mid-July [6][8]. The key dependency is whether this early-season intensity persists; a sudden shift in atmospheric pressure or cloud cover could suppress temperatures below the 35°C frontrunner, which the Polymarket book currently assigns 48–91% probability depending on the specific range tier [1].

Market depth correlates directly with deposit friction: Klarna on-ramps and SEPA withdrawal rails determine how quickly capital enters to bet against the 0% pricing. As USDC liquidity flows through these payment rails, book thickness will expand, tightening spreads on the 35°C and 36°C outcomes. The current consensus leans heavily on 35°C as the frontrunner, with 36°C as the next closest outcome, indicating traders expect a hot but not record-breaking day [1].
