Official forecasts from Météo-France, aligned with Met Office and BBC model runs, converge on a daytime peak of 28–30°C in Paris on August 17, 2026, under partly sunny skies, light northerly flow, and reduced humidity after the mid-August heatwave. This positions 29°C as the dominant outcome at the Paris-Le Bourget station, consistent with climatological August averages of 24–29°C and observed cooling from prior peaks near 33–38°C. Market-implied odds near 100% reflect this tight model agreement and real-time observational data, though modest uncertainty remains around exact timing of any cloud cover or localized advection that could shift the recorded maximum by 1°C.
