The mercury hit 34C on Court Philippe-Chatrier on Tuesday afternoon as Iga Swiatek wrapped a bag of ice around her neck between games, the four-time champion taking 90 seconds longer per changeover than her opening-round average. By the time Carlos Alcaraz closed out his second-round win over Fabian Marozsan in the night session, the on-court temperature gauge had only dropped to 27C — warmer than the daytime highs Roland Garros recorded for the entire 2024 fortnight combined.
Paris is in the grip of a “heat dome”, the meteorological phenomenon in which a ridge of high pressure traps hot air over a region for days at a time. Meteo-France has issued an orange alert for the Ile-de-France region until Friday, with forecasts of 35C on Thursday and 36C on Saturday — what would be the hottest day in French Open history, eclipsing the 35.4C recorded during Rafael Nadal’s 2003 first-round defeat by Lars Burgsmuller.
Firmer courts, higher bounces, longer points
The most visible tactical consequence has been the behaviour of the red clay itself. Tournament referee Remy Azemar confirmed the courts are being watered three times a day rather than the usual two, but the surface is still playing roughly 15% faster than the tournament average of the past five years, according to data shared by the ATP’s court-pace index team.
The ball is sitting up higher and travelling through the air quicker, a combination that has rewarded heavy topspin and punished flat hitters. Alcaraz’s average forehand revolutions per minute against Marozsan came in at 3,412 — the highest single-match figure recorded by Tennis Data Innovations at Roland Garros since they began tracking the metric in 2018. Jannik Sinner, by contrast, was visibly hunting shorter balls in his win over Richard Gasquet, finishing 19 of 24 points at the net.
For the women, the conditions have favoured the bigger servers. Aryna Sabalenka has been broken just once in two matches, holding serve in 24 of 25 attempts and clubbing 18 aces. Coco Gauff, who dropped only three games against Tereza Valentova, said she was deliberately serving wide on the deuce court more than usual because the bounce was “kicking up around the eyeline” of returners.
Bodies under siege
The medical implications have moved quickly from theoretical to acute. American world number 28 Sebastian Korda retired after two sets against Hugo Gaston on Tuesday with what his team described as heat exhaustion, the third such retirement of the tournament. Beatriz Haddad Maia required a 10-minute medical timeout for cramping during her three-set win over Greet Minnen, while qualifier Moyuka Uchijima was treated for dizziness mid-match before going on to win.
The WTA’s extreme heat rule, which permits a 10-minute break between the second and third sets when the heat stress index exceeds 30.1C, has been invoked in 11 women’s matches across the first three days. The ATP, which has only had a formal heat rule since 2022, activated it for the first time at a Grand Slam during Tommy Paul’s match against Elmer Moller on Tuesday evening.
Player nutrition teams have responded by doubling sodium intake during matches. Britain’s Cameron Norrie revealed he was consuming five litres of fluid per practice session and weighing himself before and after every workout. “You can lose four kilos in two hours out there,” he said. “If you’re not getting it back in, you’re done by the third set.”
A glimpse of tennis’s warming future
Roland Garros has historically been the most temperate of the four Grand Slams, with average highs in late May hovering around 21C. The current spike is not an isolated event — it is the third consecutive year the tournament has recorded daytime temperatures above 30C during the opening week, after just five such days across the entire previous decade.
The French Tennis Federation is already studying retractable shade structures for the outside courts, modelled on the system installed at the Australian Open’s Court 3. President Gilles Moretton confirmed in March that a feasibility study would conclude before the 2027 edition, with installation potentially in time for 2028.
For now, the players adapt match by match. Novak Djokovic, who turns 39 on Friday, opted to practise at 8am on Wednesday rather than his usual mid-morning slot, and has requested that all his matches this week be scheduled for the night session. Whether the tournament can accommodate every such request as the draw narrows is another question — one the scheduling team, like the players, is being forced to answer in conditions Roland Garros was never built for.
