(BBC) A total of 190 people crossed the English Channel to the UK on Thursday, the Home Office said.
They arrived in Kent in six boats. The French authorities stopped a further 85 people from making the crossing in three boats.
Crossings have taken place this week amid warm weather and calm seas. Almost 400 migrants made the crossing on Tuesday, including several children.
It means more than 2,500 people have arrived via small boats in March.
The figure is more than three times as many as the number of 831 migrants that arrived in March last year.
