What is the heat rule in Wimbledon and why is it in place?
Wimbledon uses the Wet Bulb Globe Temperature (WBGT) scale to ascertain if the heat rule should be enforced. The WBGT's heat index is a measure that combines air temperature, humidity and surface temperature. It is measured by a heat stress monitor.
If the WBGT is at 30.1C or higher, players will be permitted 10-minute breaks during a match. Only one player needs to request the permitted 10-minute break for it to be enforced. This rule won't be under use if the games are being played under roofs. WBGT readings at Wimbledon are measured 30 minutes prior to the start of play, at 2 pm BST and at 5 pm BST.
For best-of-five-set matches in the men's singles, the 10-minute break will be enforced the end of the third set. In best-of-three-set matches, the heat break will be taken at the end of the second set.
During breaks, players are allowed to leave the court but are not permitted to receive coaching or medical treatment.
If a game has been carried over to next day because it couldn't be finished the previous evening, then the heat rule won't be applicable if they have already played a set in a best-of-three-set match. And it won't be applicable in a best-of-five-set-match if two sets were already completed the previous day.
'Adverse weather is a key consideration in our planning for The Championships, and we are prepared for the predicted hot weather, with comprehensive plans in place for guests, players, staff and the BBGs,' the All England Club said in a statement.
Championships referee Denise Parnell explained: 'The heat rule will apply to all singles events at the Qualifying and Main Draw for The Championships 2025. These are the Gentlemen's Singles, Ladies' Singles, Boys' Singles, Girls' Singles, Gentlemen's Wheelchair Singles, Ladies' Wheelchair Singles, and Quad Wheelchair Singles.
The UK Met Office says the hottest day recorded during the Wimbledon fortnight came on July 1 in 2015, when temperatures soared to 35.7°C at nearby Kew Gardens

Alcaraz clinches Cincinnati Open as Sinner retires due to Illness
Carlos Alcaraz won the Cincinnati Open title in a little more than 20 minutes after top-ranked Jannik Sinner was forced to retire because of illness during the first set. Meeting in the final for the fourth time this year and first since Wimbledon, Sinner fell behind 5-0 in the first set with nine unforced errors. He was seen with an icepack on his head during a break and retired after playing just 22 minutes. Didn't feel great from yesterday, Sinner said. Also during the night, I thought I would recover a bit better, but it was not the case. I just tried to go out for the fans, trying to give a match. But it was not meant to be for me today. It was only the third time the Cincinnati Open men's final ended in a retirement, and the first since 2011 when Novak Djokovic stopped playing in the second set because of a shoulder injury. Wanted to wish Jannik a speedy recovery and in a few days, hopefully he's going to be OK, Alcaraz said. For myself, I am really, really happy to lift the trophy. I lost the final here in 2023. I wanted really badly this trophy. Sinner, who turned 24 on Saturday, was on 12-match winning streak and had won 26 straight matches on hard courts. He was bidding to become the first player to win back-to-back men's Cincinnati Open titles since Roger Federer in 2014 and '15. Alcaraz, who is ranked No. 2, now holds a 9-5 advantage in his matchups with the Italian. Sinner won in four sets at Wimbledon while the Spaniard won a five-set thriller at the French Open and in straight sets in the Rome Masters in May. Another classic matchup wasn't to be on Monday. Sinner received medical attention after having his serve broken for the third time and retired moments later. After the third game, I just noticed that he wasn't feeling good, Alcaraz said. I know him. I've been battling against him, having great matches, great battles. I noticed he was missing more often. It's pretty weird from him. It was only the third time the top two men's players have met in the Cincinnati Open final, the last being No. 2 Djokovic and No. 1 Alcaraz in 2022 and No. 1 Roger Federer and No. 2 Djokovic in 2012. No. 3 Iga Swiatek faced No. 7 Jasmine Paolini in the women's final later Monday. The Cincinnati Open is considered a tuneup for the U.S. Open, which begins Sunday in New York. The last two years, both the men's and women's Cincinnati Open champions went on to win the final Grand Slam tournament of the year.
