French Open Heatwave Explained: Why Roland Garros Courts Are Playing Faster in 33°C Temperatures

The heatwave sweeping through Paris has become one of the biggest talking points of the opening week of the French Open, with players reporting unusually fast court conditions and physically demanding matches at Roland Garros.

Temperatures have climbed to 33 degrees Celsius during the first two days of the tournament, conditions more commonly associated with the Paris Olympics, which were held in July and August rather than late May.

Several players have noted that the extreme heat is changing the way matches are being played on the clay courts, with balls travelling faster through the air and rewarding more aggressive styles of tennis.

Players notice faster courts at Roland Garros

Four-time French Open champion Iga Swiatek said the conditions are significantly different from previous editions of the tournament.

"It is much different. Maybe it was that hot in the Olympics, but the balls were different, so I wouldn't treat it as the same tournament," Swiatek said after her first-round win over Emerson Jones.

Australian Alex de Minaur believes the hotter weather is allowing players to play a more attacking brand of tennis on clay.

"I've always preferred hot and lively conditions to chilly on a clay court, because I feel like I can bring a little bit more of my all-court tennis on this type of surface," De Minaur said.

"It's easier to be a little bit more aggressive. The ball is jumping. I don't necessarily have to use as much spin or heaviness, and I can let the conditions do the job for me."

American Alex Michelsen echoed those sentiments, suggesting the faster conditions favour players who rely on power from the baseline.

"It's definitely good for us Americans," Michelsen said. "Generally, we're big serve, big forehand, big ground game and like to play offense. When it's super hot, the ball is moving through the air very fast. I was so happy when I saw the forecast."

Players battle extreme temperatures

Beyond the tactical changes, the heat has also created significant physical challenges for players throughout the opening rounds.

Athletes have been seen placing ice packs around their necks during changeovers, while spectators have sought relief under sprinklers around the grounds. Tournament staff watering the clay courts between sets have even directed hoses towards fans looking to cool down.

Russian-born Australian Daria Kasatkina described the weather as some of the hottest she can remember at Roland Garros.

"I don't remember the last time it was so hot at Roland Garros. Maybe one day. But we're going to have it for the whole week," Kasatkina said.

The world No. 16 also explained how the conditions can affect concentration during matches.

"You can suddenly just get out of the bench and feel that your focus dropped. So this is a battle which you have to also win. Whoever adapts better to today's conditions gets it."

Medical concerns emerge during opening rounds

The demanding conditions have already led to several health-related incidents during the tournament.

Canadian Gabriel Diallo cited the heat as the primary reason for retiring midway through his first-round match against James Duckworth on Sunday.

During Andrey Rublev's four-set victory over Ignacio Buse, both players required medical attention in the second set. Buse took a medical timeout and received additional salts and minerals, while Rublev was treated a few games later.

A ball girl also required assistance and medical attention during the same match after appearing affected by the conditions.

With forecasts predicting similarly high temperatures throughout the first week, adapting to the heat could prove just as important as adapting to the clay for players hoping to make a deep run at Roland Garros.
