It's so hot that the US Open adopted a new policy to partially close arena roofs

NEW YORK (AP) — It got so hot and humid at the U.S. Open on Tuesday that the folks in charge adopted a new policy for the rest of this year's tournament: They will partially shut the Arthur Ashe Stadium roof in extreme conditions to offer some extra shade.

The temperature climbed above 90 degrees Fahrenheit (32 Celsius) and the humidity topped 50% on Tuesday, making it the steamiest day of the two-week Grand Slam tournament in Flushing Meadows.

The change to the roof policy was made during Coco Gauff's 6-0, 6-2 victory over Jelena Ostapenko, when the conditions crossed a threshold for protecting players in the heat, but that match was over too quickly to adjust the retractable cover, tournament referee Jake Garner told The Associated Press.

The new policy is “in the best interest of fans and players,” Garner said.

An Associated Press analysis showed the average high temperatures felt during the U.S. Open and the three other major tennis tournaments steadily have gotten higher and more dangerous in recent decades, reflecting the climate change that created record heat waves around the globe this summer. For athletes, it can keep them from playing their best and, worse, increases the likelihood of heat-related illness.

Ashe was partly closed before Novak Djokovic's 6-1, 6-4, 6-1 win against Taylor Fritz. It still was muggy enough in there that Djokovic poured water over his head during one changeover; Fritz removed his shirt and placed a rolled-up towel filled with ice around his neck during another.

“I’m drenched in sweat,” Djokovic told the crowd in an on-court interview. “Just very humid conditions.”

The roof on Louis Armstrong Stadium was pulled shut some of the way after the first set of a women’s doubles quarterfinal with Magda Linette and Bernarda Pera against Jennifer Brady and Luisa Stefani.

“What went into today was we’re at a point in the tournament where all singles matches are on Ashe, so we felt we could comfortably put into a place a practice that was the same for all singles matches,” Garner said. “As the temperature and the forecast were continuing to rise, we convened and made the decision that for 2023, our policy will be when the heat rule ... comes in, we will partially close the roof at the next set break.”

The heat rule allows for a longer break between sets in singles matches when a reading that takes into account temperature and other facts crosses above 30.1 C (86.2 F).

The U.S. Tennis Association said the decision was made by Garner; he said tournament management and medical staff were involved in the discussions.

“The immediate impact is specifically that more fans were shaded,” Garner said, “and at the same time, the decision to close the roof puts the court in full shade, which does improve the conditions on court.”
