Recent ensemble forecasts from Météo-France and the ECMWF converge on a Paris high of 19–20 °C for June 9, driven by a cooler maritime air mass and persistent cloud cover from recent Atlantic fronts that limit daytime solar heating and produce a modest diurnal range. These conditions place the day slightly below early-June climatological norms of 21–23 °C for the Paris basin. Tight model agreement across leading guidance supports the market’s near-even split between the 19 °C and 20 °C outcomes, while any late-day clearing or slight warm advection could nudge readings toward the upper end of that range before official verification closes the market.
