The carnival was due to take place from Thursday, July 30, to Saturday, August 8.
Organisers say if the situation changes they will do their best to stage what they can and the raft race on Sunday, August 30, is still planned to happen.
In the meantime, we have taken a look back through our archives to previous years.
Are you one of the many people we snapped taking part in fancy dress parades and fun events?
