Recent model consensus from Météo-France and European ensembles shows a moderating high-pressure ridge over northern France, with southwesterly flow advecting milder maritime air toward Paris by July 18. This setup favors afternoon maxima near 27–29 °C at standard observing sites, tempered by possible increased cloud cover and a slight uptick in boundary-layer mixing. Urban heat-island effects could add 1–2 °C locally, yet forecast spread arises mainly from subtle differences in timing of any weak frontal passage and insolation duration. Traders therefore cluster probabilities around the 28 °C and 29 °C bins, reflecting the narrow range between official guidance and ensemble variability two days ahead of resolution.
