The BBC reported, migrants continue to arrive on UK shores after a steady stream of crossings since the weather conditions became more favourable.
The coastguard co-ordinated a search and rescue after a boat of migrants was spotted in the English Channel on Wednesday.
It comes as the home secretary prepares to discuss the number of small-boat crossings with her French counterpart.
The Home Office said “under 500” people arrived in small boats on Tuesday.
Wednesday’s search was carried out by Border Force, Dover RNLI lifeboat and the coastguard helicopter based in Lydd.
On Monday, 785 people arrived in 27 boats while French authorities stopped 378 people from making the crossing, the Home Office confirmed.
Priti Patel and Interior Minister Gérald Darmanin are both due to attend a meeting of G7 ministers in London.
She has warned that Britain could withhold £54.2m it had promised to pay France to help deal with the problem, unless more boats are intercepted.
more than 13,300 migrants have made the crossing on more than 535 boats so far this year. Just over 8,400 arrived in 2020.
Dan O’Mahoney, Clandestine Channel Threat Commander, has said: “This unacceptable rise in dangerous crossings is being driven by criminal gangs and a surge in illegal migration across Europe.
“We’re determined to target the criminals at every level.”
