Highest temperature in Paris on June 30?

Platform comparison

Market context

On 30 June 2026, Paris-Le Bourget Airport will record its peak temperature for the day, a figure that determines the outcome of this weather market. With current crowd-implied probability at 0% YES, traders are effectively betting that the temperature will fall outside the highest range being offered, despite the city currently enduring a record-shattering heatwave that has pushed temperatures to 41°C in recent days[3].

Historical data for Paris in June shows daily highs typically climbing from 69°F to 74°F, rarely exceeding 84°F, yet the current heatwave has shattered these norms with peaks reaching 104°F at Charles de Gaulle Airport on 24 June[1][2]. This extreme anomaly, which saw Paris hit 40.9°C—the hottest June temperature ever recorded—suggests that while the 0% probability reflects a belief in a return to average conditions, the recent form indicates a persistent risk of temperatures breaching the upper limits of the market range[7].

Traders must monitor the official decline forecasted for Sunday and the subsequent weekend, as Meteo France has indicated respite is anticipated starting Friday with temperatures gradually declining[3]. The critical dependency is whether the cooling trend accelerates before the settlement window closes on 30 June at 12:00 UTC, or if the residual heat from the 44°C peak recorded in parts of France sustains temperatures near the triple digits[9]. Any sudden announcement regarding the persistence of red heat alerts across the 54 departments will be the primary catalyst moving the line[5].
