Paris St-Germain will begin their Ligue 1 title defence in Brittany rather than the French capital after summer heatwaves left the Parc des Princes pitch in a condition deemed unsafe for play.

The French champions were scheduled to host Rennes on Sunday in their season opener, but Ligue de Football Professionnel (LFP) officials ruled after an inspection that the surface did not meet the minimum standards required — specifically citing concerns over player safety and physical integrity. The fixture has been reversed, with Rennes now the nominal home side.

What the heat actually did to the pitch

France recorded its hottest average country-wide day ever on 24 June, with Paris registering temperatures approaching 41°C and half the country placed under a red heat alert. Those conditions were sustained long enough to cause severe structural deterioration to the Parc des Princes playing surface. PSG acknowledged the situation was an exceptional one and said they fully understood the inconvenience caused to supporters who had planned to travel to Paris.

The club have confirmed they will relay the pitch entirely before their next scheduled home fixture — against Monaco on 4 September — so there is no suggestion of a longer-term disruption to their home programme.

PSG are not alone

The Parc des Princes is not the only top-level ground to fall victim to extreme summer temperatures this year. Spanish side Celta Vigo were forced to postpone their La Liga opener against Osasuna after a fungal disease took hold of the pitch at their Estadio de Balaídos — the result of temperatures that failed to drop below 25°C for more than three consecutive weeks, creating conditions in which the fungus thrived unchecked.

Taken together, the two incidents point to a growing operational risk for clubs whose stadiums lack the cooling infrastructure — under-soil systems, shading or artificial irrigation management — to protect natural grass through prolonged heat events. As European summers lengthen and intensify, groundskeeping decisions that once seemed routine are becoming genuinely consequential for fixture scheduling.

Context around last season

PSG won Ligue 1 by six points last season, while Rennes finished sixth and earned a place in the Europa League. On paper, then, the switch to a Rennes home game is no small ask for the champions as opening-day fixtures go — though the market will still expect Luis Enrique's side to pick up the points regardless of venue.

The broader human cost of the French heatwave is stark. Deaths in France between 22 and 28 June increased by 2,025 compared to the baseline — a rise of nearly 30% — with the Paris region alone recording a 62% increase in mortality during the same period. Against that backdrop, the LFP's decision to relocate a football match is, at minimum, proportionate.

What happens next

  • Sunday's game is played at Rennes' ground in Brittany.
  • PSG's next home fixture — vs Monaco on 4 September — is expected to go ahead as planned on a relaid pitch.
  • The LFP has not indicated any further fixtures are under review at this stage.

For now, the French champions will have to earn their first points of the new campaign on the road.

Frequently asked

Why has PSG's first game of the season been moved?
Exceptional summer heatwaves severely damaged the Parc des Princes pitch in Paris. Ligue de Football Professionnel officials inspected the surface and concluded it was not safe enough to play on, so the fixture against Rennes has been switched to Rennes' own ground.
When will PSG next play at the Parc des Princes?
PSG have said they will replace the pitch before their next scheduled home game against Monaco on 4 September 2026.
Has this happened to other clubs this summer?
Yes. Spanish club Celta Vigo were also forced to postpone their La Liga season opener against Osasuna after a fungal disease damaged the pitch at their Estadio de Balaídos, caused by temperatures that did not drop below 25°C for more than three weeks.
