Novak Djokovic experienced discomfort, Alexander Zverev had excessive perspiration issues with his footwear, and Emma Raducanu withdrew from her competition due to lightheadedness — and the concerning news for leading tennis competitors is that heightened warmth is anticipated in China in the current week.
Holger Rune from Denmark described the conditions at the Shanghai Masters as “severe,” citing temperatures exceeding 30 degrees Celsius and humidity levels surpassing 80 percent.
“Do you want a player to die on court?” Rune was heard to ask this week in the fierce conditions.
Djokovic, holding 24 Grand Slam titles, expressed on Tuesday that it was “physically very demanding” as he coped with the heat and a potential ankle injury to progress to the quarter-finals.
The 38-year-old frequently lowered himself during breaks between plays against Jaume Munar from Spain and had an episode of vomiting while on the court.
Following an unforced error, Djokovic fell to the court and remained there until a medical professional approached, after which he regained composure to secure victory in three hard-fought sets.
The path has become more accessible for the Serbian player after Carlos Alcaraz, the world’s top-ranked player, withdrew to recuperate and Jannik Sinner, the defending champion, withdrew from his match on Sunday due to muscle cramps.
Zverev, who holds the third position globally, was defeated on Monday after having to interrupt his game to switch footwear because they were saturated with perspiration.
Attendees in the primary stadium employed fans and utilized cooling packs on their temples to combat the intense humidity.
Shanghai’s primary stadium is equipped with a roof; however, it remains open unless precipitation occurs, which is not anticipated for the tournament’s duration.
Rune suggested on Tuesday that the ATP, the governing organization for men’s tennis, should implement a heat regulation at events such as the Shanghai Masters.
The ATP stated that player well-being is paramount and that it is assessing the implementation of such a policy.
At present, determinations regarding gameplay alterations due to meteorological circumstances, including heat, “are made by the ATP Supervisor present on-site, in conjunction with medical personnel and local officials,” as per the statement.
Conditions were perceived as somewhat less oppressive on Wednesday in Shanghai, though forecasts continued to indicate highs of 29 degrees Celsius.
Elevated temperatures are expected in the forthcoming days, with the highest point projected for Sunday, the final day, at approximately 32-33 degrees Celsius.
Arthur Rinderknech from France, who advanced to the quarter-finals on Wednesday, noted that the distress was not limited to the players.
He remarked, “It was equally challenging for the ball attendants, the officiating personnel, the spectators; everyone was consistently providing themselves with air circulation because of the intense heat.”
– ‘Rather than just die’ –
The circumstances present equal difficulties in Wuhan, located in central China, where the leading female tennis competitors are participating.
Temperatures in both locations are exceeding historical averages for this period of the year.
Scientists have issued recurring warnings that anthropogenic climate alterations are contributing to an increase in both the frequency and intensity of extreme weather phenomena globally.
The variance between Wuhan and Shanghai lies in the presence of a heat management protocol within the WTA.
During the WTA Wuhan Open on Tuesday, Emma Raducanu and Jelena Ostapenko, both former Grand Slam victors, withdrew from their respective matches.
Raducanu’s vital signs were assessed prior to her withdrawal from her initial match due to sensations of vertigo.
Iga Swiatek, ranked second globally, appealed to event organizers to prioritize player well-being when planning match schedules for outdoor courts without overhead protection.
“On centre court I think it’s a little bit cooler with the air conditioning and everything,” she said.
“But I hope the other matches will be scheduled at a time where girls can compete, rather than just die on the court.”
Temperatures surpassing 30 degrees Celsius led to the invocation of the WTA’s heat management guidelines on Monday, resulting in the cessation of play on exterior courts.
The heat management guidelines were also implemented for a segment of Tuesday.
These guidelines enable players to avail themselves of a ten-minute respite between the second and third sets, and permit the competition to partially or completely seal the main court’s roof to ensure player protection.
This protocol is anticipated to be implemented frequently during the present week in Wuhan, where projections indicate elevated temperatures above 30 degrees Celsius throughout the week, including the final on Sunday.
