Driven by a northward Azores high, the brief surge is expected to give way to weekend storms.

Overview

  • Météo‑France forecasts a nationwide warm spike on Friday with 35°C possible in Gironde, Lot‑et‑Garonne, Landes and Gers, around 29°C in Paris and 32°C in Bordeaux, while Brest stays near 19°C.
  • Temperatures above 30°C may be reached locally in parts of the north, including Hauts‑de‑France, Normandy, the Paris Basin and Burgundy.
  • Tropical nights above 20°C are expected from Friday into Saturday, though thresholds for an official heatwave are not met and no canicule vigilance is in place.
  • Forecasters expect a rain‑and‑thunderstorm breakdown over the weekend, with some areas still near 30°C on Saturday before a sharp drop that could leave maxima under 15°C in places next week.
  • Scientists link the growing frequency of warm Septembers to human‑driven warming, with September 2023 the hottest on record in France and wine regions reporting particularly early harvests this year.
