Current forecasts from Météo-France and ensemble models point to a minimum near 20–21°C in Paris on July 16 amid lingering warm advection and elevated dew points from the July heatwave, keeping overnight lows well above the historical early-July average of 15–16°C. Subtle differences among leading outcomes hinge on expected cloud cover, boundary-layer mixing, and any weak frontal passage that could trim or sustain the urban heat island effect by 1–2°C. With resolution just 48 hours away, traders are weighting the latest model runs and observed trends in 2-meter temperatures, producing closely bunched implied probabilities that reflect genuine forecast uncertainty rather than a single dominant scenario.
