Highest temperature in Paris on July 2?

Platform comparison

Market context

Paris will experience its second heatwave of 2026 starting Wednesday, with Météo-France forecasting highs up to 37°C in the city, a figure that sits just below the all-time record of 42.6°C set on 25 July 2019[7][2]. Long-term averages for July in Paris indicate a typical daytime maximum of 24°C, yet the current 2026 European heatwaves have already pushed temperatures to unprecedented levels, including an unofficial reading of 50°C elsewhere in France[1][6]. Given that temperatures above 40°C have occurred only three times in Paris’s history and the current forecast peaks near 37°C, the crowd-implied 0% probability for a temperature range exceeding 40°C aligns with historical rarity and the specific forecast ceiling[2].

Traders should monitor real-time updates from Météo-France and Wunderground for the Paris-Le Bourget Airport Station, as the heatwave’s intensity depends on the influx of warm air from North Africa, which could push peaks toward 40°C on Sunday[2][3]. The settlement window ends at 12:00 UTC on 2 July 2026, meaning any temperature spike occurring after the forecast window or during the night (when temperatures remain above 25°C) will not affect the resolution[2]. Recent red heatwave alerts for 54 departments confirm that high temperatures will persist around the clock, but the specific forecast for Paris remains capped below the 40°C threshold, making a breach of that range highly improbable unless an unexpected surge occurs[3].
