Heat wave at French Open impacts the clay courts and has fans begging for water

PARIS (AP) — Tennis players at the French Open say they haven’t experienced conditions this hot at Roland Garros since the Paris Olympics.

And the 2024 Olympics were held in July and August.

Temperatures for the opening two days of the clay-court Grand Slam have soared to 33 degrees C (91 F) — far beyond normal for late May in the French capital. And it’s forecast to stay that way for the entire first week.

Besides making it uncomfortable for fans and players alike, the sultry conditions have also created faster conditions on court — changing the pace of the game.

“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,” four-time French Open champion Iga Swiatek said after routing Emerson Jones 6-1, 6-2 in the first round on Monday.

Players have been putting bags of ice around their necks on changeovers to stay cool, while fans are refreshing themselves under sprinklers.

When workers water the clay courts between sets, they have taken to directing their hoses at spectators begging to be doused, too.

“I don’t remember the last time it was so hot at Roland Garros,” Russian-born Australian player Daria Kasatkina said after beating Zeynep Sonmez 6-4, 6-4. “Maybe one day. But we’re going to have it for the whole week.”

Kasatkina said the energy-sapping temperatures made for more up-and-down matches.

“You can suddenly just get out of the bench and feel that your focus dropped,” she said. “So this is a battle which you have to also win. … Whoever adapts better to today’s conditions gets it.”

Canadian player Gabriel Diallo said the heat was the main reason why he retired midway through his match against James Duckworth on Sunday.

Both Andrey Rublev and opponent Ignacio Buse called for the trainer on separate occasions during the second set of their match on Monday.

Buse took a medical timeout and had salts and minerals added to his water bottle as a stethoscope was placed on his chest. Rublev received treatment a few games later.

The French Open is usually cool compared to the heat at the Australian Open and U.S. Open.

But like in Australia and New York, the French Open has adopted an extreme weather policy.

If the Wet Bulb Globe Temperature (WBGT) — which takes into account temperature, humidity, sun, wind and other factors — reaches 30.1 degrees C (86 F) or higher, 10-minute cooling breaks can be installed between the second and third sets for women’s matches and between the third and fourth sets for men’s matches.

If the WBGT hits 32.2 C (90 F), play is suspended. It would require an air temperature of about 38 C (100 F) for play to be suspended.

Some players were embracing the hotter air.

“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,” Australian player Alex de Minaur said after beating Toby Samuel 6-4, 6-4, 6-2.

“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. And it’s quite physical. I don’t mind the heat,” De Minaur added.

Same goes for American player Alex Michelsen, who eliminated Alexander Shevchenko in straight sets.

“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.”

The risk of a catastrophic explosion at a damaged chemical tank in Southern California has been eliminated following a close overnight inspection that confirmed a crack in the tank relieved pressure and cooled the chemical, authorities said Monday.

Officials said crews conducted tank temperature checks at night to reduce risks to firefighters, avoiding daytime operations when heat from the tank made conditions around it most dangerous. The overnight mission allowed crews to verify the crack and confirm temperatures were falling, Orange County Fire Authority division chief Craig Covey said Monday morning.

Covey said the results of overnight evaluation of the tank — that the temperature inside had dropped and that pressure had been released — was “incredibly positive news.”

However, evacuation orders remained in place for about 50,000 people in Garden Grove, California, located south of Los Angeles.

Covey said falling temperatures and the release of pressure from the tank were allowing officials to “turn the corner on this incident” after days of concern about a possible explosion.

There has been no chemical leak as of early Monday, but the Orange County Fire Authority said the risk to public safety is “ongoing.”'

After the tank overheated Thursday and began venting vapors, firefighters have repeatedly sprayed the tank with water in an attempt to cool the chemical inside, methyl methacrylate, which is used to make plastic parts.

The tank's interior reached 100 degrees (37.7 Celsius) Sunday, an increase of 10 degrees Fahrenheit (5.5 Celsius) since Saturday, according to Democratic state Sen. Tom Umberg. On Monday, Covey said the temperature fell to 93 degrees F (33.9 degrees C).

Gov. Gavin Newsom declared a state of emergency Saturday and said he asked President Donald Trump to issue an emergency declaration to bolster federal support for local and state officials.

The tank at GKN Aerospace Transparency Systems, which makes parts for commercial and military aircraft, holds 6,000 to 7,000 gallons (22,700 to 26,500 liters) of methyl methacrylate used to make plastic parts.

The first goal of firefighters was to cool off the chemical inside the tank to prevent a leak or explosion.

Drones were monitoring temperatures at 10-minute intervals to watch for any spikes. Containment barriers were set up to prevent the chemical from getting into storm drains or reaching creeks or the nearby ocean in the event of a spill, Covey said earlier.

As the interior temperature rises, methyl methacrylate converts from a liquid to a gas and increases the pressure, according to Purdue University engineering professor Andrew Whelton, who had said earlier that the crack could mean product or pressure is being released, reducing the chance of explosion.

“Think of a soda can. If you leave it in a hot car it can explode,” Whelton said. “But if you put a hole in the can, the product is released and the can itself doesn’t explode.”

An explosion that could spread the chemical over a broad area and send shrapnel flying would be the worst-case scenario, he said.

Aerial photos taken by The Associated Press showed streets in the area were empty Sunday, while several evacuation shelters were open. At a high school in neighboring La Palma, people slept in cars or on mats and sleeping bags on the asphalt.

Garden Grove is next to Anaheim, home to Disneyland’s two theme parks, which were not under evacuation orders. Park officials said they were monitoring the situation.

Exposure to methyl methacrylate can cause serious respiratory problems, neurological problems and irritation to the skin, eyes and throat, according to fact sheets about the chemical.

Whelton said if an explosion occurs, it will be crucial to conduct detailed air monitoring specifically for methyl methacrylate and not just generic tests for volatile organic compounds as officials did after a 2023 train derailment in East Palestine, Ohio, which released more than 115,000 gallons (435,000 liters) of vinyl chloride after officials blew open five tank cars and burned the chemical.

Orange County health officials said the chemical is easy to smell and people may notice it over a large area without being harmed.

Some Garden Grove residents filed a class-action federal lawsuit Saturday against GKN Aerospace Transparency Systems, which operates the facility where the tank is located. Lawyers for the residents argued that regardless of what happens, property values in the surrounding community are sure to be impacted.

GKN Aerospace did not comment on the lawsuit but has apologized to residents and businesses forced to evacuate. It said Sunday it was “working around the clock to mitigate the risk of a leak.”

GKN Aerospace agreed in 2025 to pay state regulators more than $900,000 to settle violations involving recordkeeping, permitting issues and nitrogen oxide emissions, according to a report on the South Coast Air Quality Management District website.
