Tokyo 2020 Olympics organisers have cancelled two days of rowing with adverse weather conditions expected to hit Japan's capital.
It comes on the same day an extreme weather policy was activated in the tennis tournament. Temperatures reached 32C in Tokyo on Sunday.
On Saturday, world number one Novak Djokovic and Daniil Medvedev both complained about the heat during their first-round wins.
The International Tennis Federation activated its policy once the reading went above 30.1C, with players given a 10-minute break between the second and third sets, and change of ends and set breaks were also extended by an extra 30 seconds.
