Persistent heatwave conditions driven by a strong high-pressure system over western Europe are keeping minimum temperatures elevated in Paris ahead of June 24. Recent model guidance and Météo-France outlooks show daytime maxima near 39–40 °C on June 22–23 with overnight lows holding around 22–23 °C amid light easterly winds, clear skies, and limited radiative cooling. This warm air mass, combined with the urban heat-island effect and high soil moisture from prior weeks, reduces the typical diurnal range and makes sub-22 °C readings unlikely while capping upside potential above 26 °C. Ensemble spreads remain modest two days out, supporting the tightly clustered market-implied probabilities around 23–25 °C. Updated model runs and the next Météo-France briefing will provide the clearest signal on any late adjustment to the minimum.
