A record 1,295 migrants arrived in the UK on Monday after crossing the Channel, according to Government figures.
This is the highest daily total since current records began in 2018.
Some 27 boats made the trip, according to interim Ministry of Defense (MoD) data, suggesting an average of about 48 people per boat.
The previous highest daily number was 1,185, on November 11 2021.
More than 22,600 people will arrive in the UK after navigating busy shipping lanes from France in small boats such as dinghies by 2022, according to the figures.
At the corresponding point in 2021, the cumulative total was less than 12,500.
Overall, 28,526 people crossed last year.
So far in August 6,271 people have been recorded crossing. This is higher than any monthly total for the year so far. To date, the highest monthly total for crossings on record is November 2021 (6,971).
Crossings continued on Tuesday amid windy conditions in the Channel.
The Border Force cutter Hurricane was seen rescuing around 40 people, including a family with two small children.
They were brought ashore at Dover, Kent, around midday after many other people were thought to have made the crossing earlier in the day.
Parents carried a toddler, who was screaming and crying, to safety, while a member of the military staff was seen holding another child in his arms.
Some of the young men waved to members of the press as they arrived while others carried their belongings in bin bags.
It has been four months since Home Secretary Priti Patel announced plans to send migrants to Rwanda in a bid to block Channel crossings.
Since then, 17,402 people have arrived in the UK after travelling.
On April 14, Ms Patel signed what she described as a “world-first” deal with Rwanda under which the east African country will accept migrants deemed by the UK to have arrived “illegally” and therefore inadmissible under the new immigration rules.
But the first deportation flight – due to depart on June 14 – has been grounded amid legal challenges.
Some asylum seekers, Public and Commercial Service unions and charities Care4Calais, Detention Action and Asylum Aid are challenging the legality of the Home Office’s policy, with further court hearings due in September and October.
Steve Valdez-Symonds, director of refugee and migrant rights at Amnesty International UK, said: “Despite the Government’s shameful posturing and draconian refugee policy-making, the simple fact is that people including children fleeing war and persecution will continue to make dangerous journeys – whether by boat or other means – if the Government refuses to provide safe routes for them.”
A Government spokesman said: “The increase in dangerous Channel crossings is unacceptable. Not only are they a flagrant abuse of our immigration laws but they will put the lives of vulnerable people at risk, who are being cruelly exploited which are criminal gangs.
“Our new Nationality and Borders Act destroys the business model of vicious criminals, through tougher sentences for those who facilitate illegal entry into the country, with 38 people already arrested and facing further action from when it became law.
“Under our new Migration and Economic Development Partnership in Rwanda, we continue to prepare to relocate people who make these unnecessary and illegal journeys, helping to save lives by preventing others from crossing .”
