Current forecast models from Météo-France and ensemble guidance indicate mostly clear skies and light winds over Paris on June 13, favoring nocturnal radiative cooling that supports overnight lows centered near 12–14°C. This aligns with climatological baselines for mid-June, when average minimum temperatures range 12–15°C amid typical anticyclonic conditions. Model consensus shows limited spread due to stable high pressure, though minor variations in boundary-layer moisture or wind speed could shift the exact minimum by 1–2°C. With resolution hinging on the official Paris-Montsouris station reading, traders weigh these factors against the narrow historical range for the date, resulting in tightly clustered implied probabilities across 12–15°C outcomes. Updated runs from European and global models are expected within 24 hours.
