Deputy Assistant Commissioner Andy Valentine said: "We have more than 1,300 public order officers ready to deploy across London today in addition to thousands already working in our communities.
“We will not tolerate any disorder and will make arrests."
He said the force was using mounted units, dog handlers as well as intelligence experts and evidence gatherers.
"We will be using retrospective facial recognition to help officers identify those behind criminal disorder. This technology can be used even when offenders are wearing masks."
He added: "Our thanks goes to Londoners who condemn the hateful and divisive behaviour which is fuelling significant concern among our communities.
“Everyone can play a role by not sharing inflammatory online speculation and giving our officers space to undertake their important duties.
"We also ask parents to think carefully about where their children are today and in coming days. No-one wants to be caught up in potentially violent and criminal behaviour.
"It is our privilege to be part of a city pulling together at an uncertain time. You will see more officers on patrol. If you are concerned, or need help, speak to them. They are there to help."
