More than 200 people were rescued from the Channel and brought ashore on Wednesday, latest figures show.
Warm weather and low winds provided ideal crossing conditions and, the Ministry of Defence said, six boats were intercepted and 233 people brought to shore.
On Thursday the crossings continued, with the Border Force ship Hurricane bringing four children and two adults ashore in Dover.
It was at least the second ship to bring people ashore in the town on Thursday, with more expected throughout the day.
On Wednesday, two Border Force boats brought approximately 150 people ashore including around 30 children.
However, Border Force and RNLI ship activity suggests some people may have been taken ashore in Dungeness or Ramsgate.
The people are then put on buses and sent to processing centres.
The majority of people brought ashore in Dover on Wednesday were men aged from their late teens to their 30s or 40s but there was also a number of women and young children.
The countries of origin of the people coming ashore in Dover included Afghanistan, Iraq and Egypt.
Crossings have continued despite the possibility of migrants being sent to Rwanda – although the first planned flight to the African country was grounded at the last minute on Tuesday.
It is not yet known when the next flight to Rwanda is expected to take place but Justice Secretary Dominic Raab hinted the second flight may not happen for weeks.
Asked on LBC Radio when the first migrant flight may depart for Rwanda, Mr Raab said: “I don’t think I can give a precise date.
“The important thing to understand is that this ongoing legal challenge has been around the injunctions. There is a full hearing due in a few weeks. All the issues can be aired there.
“I would expect and I hope, because we are confident of our position, that we get clarity from the UK courts and then we can proceed.
“But of course now there is the question mark about whether Strasbourg will intervene so we will need to see how that goes.”
The first flight initially planned on Tuesday night was halted fllowing an injunction from the European Court of Human Rights.
Following the intervention, Home Secretary Priti Patel claimed she was disappointed and found the decision “surprising”.
Soon after, Downing Street confirmed the Government is considering a withdrawal from the European Convention on Human Rights, after the Prime Minister hinted it may be necessary to change certain rules to allow future departures.
Commenting on leaving the convention, which the UK helped draw up after the Second World War, a No10 spokesperson said: “We keep all options on the table as part of our work to address the issues raised by the repeated and sometimes meritless claims that we see consistently with removal flights, while obviously making sure that we continue to protect the vulnerable.
“We will do whatever it takes to deliver this new approach, including being prepared to explore any and all further legal reforms which may be necessary.”
