Wimbledon experienced its hottest day of the Championships on Sunday, with temperatures climbing to 31 degrees Celsius (87.8 F), turning the All England Lawn Tennis and Croquet Club grounds into a significant test of endurance for players, officials, and spectators. This intense heat prompted a yellow heat health alert for London, issued by the UK Health Security Agency and set to remain in effect until Saturday evening.
Attendees were seen using fans and umbrellas to combat the rising temperatures as they queued for matches featuring top players like Novak Djokovic, Jannik Sinner, and Aryna Sabalenka. On court, players were provided with specialized ice towels, and over 100 water stations were established across the venue to help participants and spectators stay hydrated.
Wimbledon operations director Michelle Dite emphasized that while organizers have intensified welfare measures, spectators also bear responsibility for managing their well-being in the heat. "It's about people preparing for their day. It's about putting your sun cream on, about bringing your own water," Dite stated. "We let people bring their own water in, their own food and drink. It's about taking time out and asking people to take some responsibility."
She added that the venue has increased available shade and shelter, with many people seeking cooler air in restaurants. "We have upped our shade and shelter here for the public," Dite noted. "We encourage people to take personal responsibility."
Wimbledon is continuing to invest in long-term infrastructure to address the increasing frequency of extreme heat during British summers. "Every year we're looking to improve it," Dite said, mentioning enhancements like a retractable roof on the Tea Lawn and additional cover in various areas.
The tournament's court services team is also on standby to assist ball boys and girls. Winston Sedgwick, assistant manager of court services, recounted an incident last Thursday where a ball boy on court 7 became unsteady due to the heat and had to be taken off, given ice packs, shade, and fluids. "That's something we have to do and we're quite happy to do it," Sedgwick said.
For the first time this year, Wimbledon introduced handheld fans for sale on-site, priced at £20, reflecting the surge in demand for heat-relief items. The tournament is also distributing hundreds of thousands of free sun cream samples in partnership with La Roche-Posay to aid those in queues and on the grounds.
The extreme heat on Sunday brought Wimbledon close to activating its Extreme Heat Rule. This rule allows for a 10-minute break in singles matches if the tournament's heat stress index surpasses a set threshold. The break can be taken before the fourth set in men's matches and before the deciding third set in women's singles. Officials assess the conditions using a combination of air temperature, humidity, and court surface temperature.
The hottest day ever recorded at Wimbledon was July 1, 2015, when temperatures reached 35.7C (96.3F). An on-site pharmacy offers 50 SPF suncream for £27.50.
