Recent model consensus from Météo-France and European ensembles indicates a high near 28–29°C at Paris-Le Bourget on August 1, driven by moderate southerly flow under high pressure with limited cloud cover and modest urban heat-island enhancement. This places the peak slightly above early-August climatology (roughly 24–26°C) yet well below the extreme values seen in the June 2026 heat wave. Latest short-range runs show minimal day-to-day shift, with only small spread between 27°C and 30°C scenarios, explaining the heavy concentration of market-implied probability on the two central outcomes. Traders are monitoring the final afternoon observations and any last-hour model updates for resolution.
