In October, the numbers crossing passed the 29,437 who made the journey during the whole of last year.
GB News travelled to the makeshift migrant camp at Grand Synth near Dunkirk on Tuesday morning.
The channel's Kent producer counted more than 500 migrants in that one camp alone.
Many were being fed by local activist groups and charities.
The numbers in and around the coastal camps fluctuate, depending on weather conditions and the schedule for launches prepared by the people smugglers.
Many migrants are camped further inland but travel to the coast in the hours and days ahead of their planned sailing day.
Early on Tuesday morning, French police intercepted an attempted small boat launch from a beach at Sangatte near Calais.
The boat, engine and dozens of lifejackets were discarded by the smugglers as they ran off when police moved in to foil the launch.
Winds in the Channel are not expected to die down until later this evening and into Christmas morning.
Border Force has been placed on a heightened state of readiness, to prepare for five to six days when the weather will be calm enough for small boat launches.
One small boat smuggler has offered migrants a “Christmas special” deal to illegally cross the Channel.
The smuggler, who uses the name 'Salar' on the Telegram messaging site.
He wrote that he had 15 places available on one small boat.
He said: “From the 25th until the 29th, there will be special offers as the weather is also good – God willing, you will be in England before the new year.”
