Heatwave Timeline
From 19 June, a second 2026 heatwave swept mainland France, pushing temperatures above 30 °C. Forecasts expected peaks of 40 °C on Sunday 21 June and up to 42 °C on Monday 22 June in Paris, Orléans and Nevers, prompting orange alerts for 60 departments and red alerts.
Background
The event follows a hot May that broke records and recalls the August 2003 heatwave, which caused over 14,800 deaths. Scientists attribute the rising frequency of such extremes to climate change.
Key Figures
President Emmanuel Macron called for vigilance; Rist advised against alcohol and activity. Paris mayor Emmanuel Grégoire questioned proceeding with the Fête de la Musique; police prefect Patrice Faure cancelled 11 outdoor sports events. Météo-France forecaster Christelle Robert announced the heatwave’s gradual onset.
Data
Orange alerts covered 60 of 96 departments, affecting 41 million people. Highs reached 40.4 °C in Saint-Florent-sur-Cher. Forecasts projected 41 °C in Paris and 42 °C in Nevers. SNCF cancelled 71 intercity trains (?0.1 % of daily services).
Public Impact
Municipalities in Biarritz, Limoges, Brive-la-Gaillarde and Nanterre cancelled the Fête de la Musique. Schools altered timetables, postponed oral baccalauréat exams, and Tours mayor Emmanuel Denis announced closures at 40 °C. Paris opened the Canal Saint-Martin for supervised swimming.
Official Responses
Macron urged vigilance for seniors; Rist advised against alcohol and activity. Météo-France described the heatwave as widespread and intense, warning of red alerts. SNCF framed cancellations as prevention; EDF reduced output at four nuclear plants due to warm river water.
Criticism
Tour mayor Emmanuel Denis argued schools should close at 40 °C for safety. Guillaume Perrin criticized reliance on water intake alone in schools. Grégoire’s remark on police resources to stop swimming sparked debate.
Ground Reports
A 30-year-old man died of cardiac arrest on a Paris track on 18 June. Residents swam in the Canal Saint-Martin under supervision. SNCF cut services on routes Paris-Orléans-Limoges-Toulouse, Paris-Clermont-Ferrand and Bordeaux-Marseille.
Conflicts
Sources report orange alerts for 55, 60 or 26 departments, showing data inconsistencies. Forecasted peaks vary between 40 °C, 41 °C and 42 °C. Reliability scores differ across outlets, and some figures lack verification.
