Channel smuggling routes stretch south as migrants face longer, riskier crossings

A growing number of migrants are attempting to reach the UK in small boats by setting out from beaches much further south and west of Calais and Dunkirk, according to French authorities — a sign that the geography of Channel smuggling is widening even as overall crossing numbers fall.

Border Force vessels intercepted one boat last week that had departed from Normandy and spent more than 30 hours at sea before being escorted back to Dover. Journeys of that length, in an open inflatable craft, carry far greater risks than the short, direct passages that made up the bulk of Channel crossings in recent years.

Officials in Seine-Maritime say the shift is measurable. Attempts to cross from that department — which encompasses the Dieppe coastline and stretches towards Le Havre — have reached 58 so far this year, compared with 30 in the whole of last year. Attempts from Normandy itself had been rare until recently.

The trend runs against the background of a sharp fall in arrivals. UK government figures show a significant decline in small boat arrivals this year, and the BBC's own analysis indicates a 42% drop compared with the same period last year. Yet the coastline being used by smugglers appears to be getting wider rather than narrower, effectively relocating the problem from the traditional epicentre around Calais to longer, more exposed stretches of the Channel.

A second case illustrates the pattern. Earlier this month, lifeboat crews from the Isle of Wight met a migrant boat that had set out from the Cherbourg area. Those departure points sit almost 80 miles (128 km) from the beaches where many small boats have landed in recent years, meaning those on board face a crossing of several hours in poor weather rather than a brief hop.

Audrey Baconnais-Rosez, the local government representative in Seine-Maritime, said the department was seeing both a rise in the number of attempts and a steady movement of departure points further from northern France. She added that authorities are "managing to stop half of them" — a notable admission that the remainder of the attempts succeed in reaching British waters.

Enforcement has been scaled up in response. The number of gendarmes patrolling the coast between Dieppe and the area approaching Le Havre has been increased, with roughly 50 gendarmes now working the coastline and close to 20 police officers based in Dieppe and its surroundings, according to Baconnais-Rosez.

Not all of the attempts involve open water. The same official said smugglers are also continuing to use ferry services to Newhaven in Sussex, with French authorities intercepting those travelling on the boats and subsequently pursuing prosecutions.

Dr Peter Walsh, a senior researcher at the University of Oxford's Migration Observatory, said it is highly plausible that the new routes are a direct consequence of police disruption of launching sites in northern France. He noted that long-distance departures are far from ideal for the vessels involved, which are typically not designed for open-ocean conditions.

"Some of these journeys would not be 20 miles but 50 miles or even more," Walsh said, adding that the extended time at sea "substantially increases the danger of course on board the boats" for passengers who may already be distressed, cold or dehydrated before departure.

Marine safety consultant David McFarlane said the longer the voyage, the greater the likelihood of meeting hazardous sea states, and that hazards can develop faster than passengers expect. He explained that a low pressure system building over the Atlantic can drive up swell in advance of the strongest winds, causing seasickness that can quickly lead to dehydration among people already weakened by stress and exposure.

He added that wind can rise very quickly and waves in the Channel can reach heights of around 3.5m (11ft). In such conditions, the risk is that an overcrowded boat is swamped by seawater, carrying what he described as the obvious danger of death by drowning or exposure.

The scale of the phenomenon that these departures sit within remains substantial. Between 1 January and 27 September 2026, 19,135 people crossed the Channel by small boat from France. That is the fifth-highest total recorded by the same point in the year since official counts began in 2018 — when just 299 people arrived by boat. Annual totals have since risen to 8,462 in 2020, 28,526 in 2021, a record 45,755 in 2022, 29,437 in 2023, 36,816 in 2024 and 41,472 in 2025.

Small boat crossings have been the most common way for people to be detected entering the UK illegally since 2020, and nearly all those who arrive this way claim asylum. Under international law, they are permitted to remain in the country while their application is considered. Between July 2025 and June 2026, small boat arrivals accounted for 40% of asylum applications filed in the UK.

The vessels themselves are also getting more packed. Boats that reached the UK between 28 September 2025 and 27 September 2026 carried an average of 67 people each — more than double the average recorded in 2021. Experts warn that such overcrowding makes crossings considerably more hazardous, and the United Nations recorded at least 84 deaths among people attempting the Channel crossing in 2024.

Taken together, the picture presents policymakers with a difficult trade-off. Disruption of the well-established northern routes appears to be working, with arrivals falling, but the same enforcement push is pushing departures south, where journeys are longer, conditions are more exposed and the risk of tragedy is higher. Unless French patrol numbers keep pace and the push displaces rather than prevents crossings, the reduction in totals may come at the cost of a greater human toll at sea.
