Recent forecasts from Météo-France and European models indicate a heatwave peaking near the June solstice, with Paris highs projected at 36–38°C on June 21 under clear skies, light winds, and dry high-pressure conditions that maximize daytime solar heating. Trader sentiment clusters tightly around these values because ensemble guidance shows only modest day-to-day shifts in 850 hPa temperatures and boundary-layer mixing, while the historical record high of 37.1°C sets a plausible ceiling. Minor divergences arise from potential thin afternoon cloud development or slight variations in wind direction that could trim or enhance the peak by 1–2°C at official stations. Updated model runs and Météo-France briefings over the next 48 hours will likely tighten the distribution before resolution.
