Highest temperature in Paris on July 15?

Platform comparison

Market context

Paris will record its peak daytime heat on 15 July 2026 at the Paris-Le Bourget Airport Station, with the market resolving to the Celsius range containing that highest temperature. The settlement hinges on a single day’s meteorological data sourced from Wunderground, closing at 12:00 UTC the following day.

Historically, mid-July highs in Paris average 26°C, though daily peaks have ranged from 20°C to 43°C in extreme cases [2]. With the crowd-implied probability for a “YES” outcome at 0%, the market currently prices in a near-certainty that the temperature will fall outside the specific range offered, suggesting traders expect either a notably cooler day or a spike beyond the upper bound of the listed bracket. This aligns with recent summer volatility where heatwaves have pushed temperatures above 40°C, while sudden Atlantic fronts have occasionally dropped highs below 22°C.

Traders should monitor the European Centre for Medium-Range Weather Forecasts (ECMWF) 72-hour outlook and any Meteo France heatwave bulletins, as these dictate short-term temperature trajectories. A recent report from Le Monde notes that France’s 2026 summer has already seen record-breaking early heat, increasing the likelihood of another spike [2]. For users on polymarket-klarna.co.uk, deposit friction via Klarna or SEPA could delay entry into the book before the final forecast update, while USDC withdrawals remain the fastest rail for exiting positions once the Wunderground data locks.
