Armed officers will be deployed to the city centre, Etihad stadium and Metrolink stations across the city.
There will also be increased security checks at the Etihad stadium. Concertgoers are advised not to bring bags and to arrive early to allow plenty of time to get in.
As part of the Manchester Day parade, a special tribute will be paid to the victims of the arena bombing on May 22.
The tribute will be an additional element at the front of the parade, and will also honour the efforts of the emergency services in the days after the attack.
