Highest temperature in Paris on July 9?

Platform comparison

Market context

Paris is entering its second major heatwave of 2026, with Météo-France forecasting highs near 37°C by mid-July, just shy of the city’s all-time record[1]. This follows a historic heat event in late June that pushed France’s national thermal indicator to 29.8°C, the highest ever recorded for any month[8]. Given that July 9 falls within the projected 12-day window of this new extreme heat phase, which is expected to persist past July 14, the current 0% YES probability for a high-temperature outcome appears misaligned with the meteorological reality[5].

Traders should monitor daily Météo-France bulletins and Wunderground updates for the Paris-Le Bourget station, as temperatures in northern France are projected to reach 35–38°C, with feels-like values climbing higher[2]. While southern regions may hit 40–41°C, Paris remains within the core zone of this persistent heatwave, and nighttime lows staying above 25°C will limit cooling[2]. The key catalyst is whether the heatwave intensifies beyond current forecasts; any deviation toward 40°C in Paris would immediately invalidate the current market stance, making real-time weather data essential for accurate positioning.
