The Met says it will focus on preventing violence, protecting women and girls and keeping crowds safe.
Kensington and Chelsea Council is working with police and organisers on safety and crowd management measures.
More than 330 people have also been banned from attending Carnival under bail conditions.
On Wednesday morning, Met officers worked with officers from Greater Manchester Police to carry out raids on multiple London addresses, arresting seven people on suspicion of robbery.
It is alleged that they’re part of a gang that targets music events and festivals to commit serious offences.
Information suggests they have previously targeted Carnival and may have had plans to do so again.
Police have also worked with the Probation Service to ensure that registered sex offenders who they believe are likely to attend public events have conditions attached to their licences preventing them from attending Carnival.
Officers have been visiting businesses (including hotels, pubs/restaurants, fast food outlets, phone and vape shops, supermarkets etc) in the surrounding areas to raise awareness of the risk of child sexual exploitation and trafficking, advising on the warning signs to look out for and what actions to take.
In the Westminster area alone, more than 90 businesses were visited.
Chief Superintendent Dominique Ioannou, British Transport Police (BTP), said:
“We’re proud to be working alongside our policing and transport partners once again to help keep people safe as they travel to and from Notting Hill Carnival, which this year celebrates its 60th anniversary.
“We know London’s transport network will be exceptionally busy throughout the weekend, and we have a comprehensive policing plan in place, including specialist resources and highly visible patrols who will be working across the network to help ensure people can focus on enjoying the event.
“We want everyone attending Carnival to enjoy themselves, look out for one another, and treat fellow passengers and transport staff with respect. We also encourage the public to remain vigilant while travelling and to report anything that doesn’t feel right. Speak to a police officer or member of staff, or you can text us discreetly on 61016.”
