Wimbledon has reached the semifinal stage, with Carlos Alcaraz, Jannik Sinner, Taylor Fritz and Novak Djokovic all in action on Friday.

The forecast suggests that Wimbledon 's rarely-used heat rule may be called into action on Saturday. It allows for a 10-minute pause between the third and fourth set of men's matches, or between sets two and three of women's matches.

There is a 'heat rule' in place at Wimbledon which will see a ten-minute break taken between the second and third set when the heat stress index is at or above 30.1C.
