Recent ensemble forecasts from the ECMWF and Météo-France indicate a strengthening high-pressure ridge over northern France will deliver largely sunny conditions and light southerly flow to Paris by August 8, supporting daily maxima centered on 30–31 °C. These model runs show minimal cloud cover and negligible precipitation risk after early morning, allowing strong daytime heating consistent with late-summer climatology for the region. Market-implied probabilities reflect this consensus, with traders assigning the highest weight to 30 °C while retaining meaningful probability on 31 °C pending the next high-resolution updates. The primary remaining uncertainty lies in exact boundary-layer mixing and any subtle shifts in the ridge axis that could alter peak temperatures by 1–2 °C.
