Another 36 migrants including women and children braved ice and snow warnings to make the latest crossing from France to the UK.
Border Force detained the group during the early hours on Saturday who battled the dangerous conditions in a small boat over the Channel.
They were brought into Dover Marina in Kent and escorted up the gangway to be processed by immigration enforcement.
Groups were seen huddling under light blue blankets for warmth as temperatures plummeted to 39F (4C).
As many as two children, who appeared to be under the age of 10, were hoisted out of the back of the Border Force cutter by an adult migrant.

Three children have been rescued from the English Channel after Border Force sent out a boat to stop crossings following the arrival of 160 migrants on the weekend.
They were among 30 people picked up in French waters, after their boat was spotted by a ferry.
Border Force officers were also active off the UK coast on Monday.
It comes after at least 160 migrants successfully crossed to Kent and Sussex over the weekend.
Calm winds at the coast saw several small boats make it into UK waters across the two days despite the cold weather.
A number of children are believed to have been among a few dozen migrants who were brought to Sovereign Harbour in Eastbourne, East Sussex, on Saturday.
