This is the highest average since records began in 2018.
The average number of migrants crossing the Channel per boat last month was the highest on record, figures show.
Some 3,299 people made the journey in July in 63 boats – an average of around 52 migrants per vessel.
This is the highest average since records began in 2018, according to PA news agency analysis of Government data.
The third highest average (47) was reached in October last year when 147 boats carried 6,900 people in a month.
Provisional Home Office figures show 14,732 migrants have arrived in the UK after crossing the Channel so far this year. But no arrivals have been recorded in nearly a week amid poor weather conditions at sea.
The 2023 total to date is 10% lower than the 16,434 recorded from January to July last year.
