On July 5, authorities banned all spectators from the final 44 km of Stage 3 and restricted access to the route . The publicity caravan was also cancelled for the French portion of the stage . Organisers have not ruled out a full stage cancellation or further parcours changes . A final decision is expected before the stage start on July 6 .
If cancelled, it would be the first-ever Tour de France stage cancelled due to a wildfire and only the second stage cancellation in history not caused by war (the other was the 2019 avalanche at stage 19) .
A severe heatwave struck France in late June, with Météo-France recording 44.3°C (111.7°F) in Pissos on June 23 — the hottest day in France since records began in 1947 . Bordeaux hit 42.1°C and Paris set a June record of 40.9°C .
At its peak, 72 of France's departments were placed under red (maximum) heatwave alerts . The government shut 3,500 schools and shortened hours at 10,000 more . Forecasts indicate another extreme heatwave could arrive during the Tour's first week, pushing temperatures back above 40°C across southern France .
The UCI's Wet Bulb Globe Temperature (WBGT)-based strong-heat protocol may be triggered for the first time in the men's Tour, which can mandate extra cooling measures, extended feeding zones, or stage neutralisation .
On July 3, the French Interior Ministry issued a directive authorising regional prefects (state representatives in each department) to cancel Tour de France stages if a red heatwave alert is declared .
Interior Minister Laurent Nunez announced guidelines allowing prefects to take measures including stage cancellation "in exceptional circumstances and in consultation with the race organisers" . This marks the first time French authorities have formally delegated such cancellation power to prefects for the Tour, reflecting the escalating risks of extreme heat .
The 2026 European heatwave has been unusually intense and widespread. Italy and Spain also reported significant temperature records and heat-related deaths . The UK extended its own heat health warnings . In France, the heatwave had already forced cancellation of outdoor sports events and restricted alcohol sales during the Fête de la Musique in late June . The combination of continuing high temperatures, dry conditions, and active wildfires across southern Europe creates a volatile backdrop for the entire first week of the race .
