Mr Farage said Medway in Kent was a “very strong Ukip voting area”.
The GB News presenter said his take from the local election results so far is that Red Wall-style voters are switching back to Labour after flocking to Boris Johnson in the 2019 general election.
Mr Farage said: “Local election results coming in, it’s early yet, most will be counted today.
“But interesting to see somewhere like Medway after 23 years of Tory rule now going to Labour.
“Medway is a very strong Ukip voting area, Rochester part of it which was a Ukip parliamentary seat, we won it in a by-election.
“The evidence says to me that Red Wall-style voters are going back to Labour. That’s the big takeout I’ve got so far.”
Labour snatched Medway off the Tories and will run the Kent council for the first time since 1998.
Conservative councillor Alan Jarrett, who will no longer lead Medway after Labour took control, said Downing Street must “get their act together on a number of fronts”.
Sir Keir this morning headed to Medway to celebrate Labour’s local election results and jubilantly declared he is in course to take the keys to Downing Street at the next general election.
To the cheers of Labour activists, he said: “You didn’t just get it over the line, you blew the doors off.”
Sir Keir said there have been “fantastic results across the country” in “places we need to win”, citing victories in Plymouth, Stoke and Middlesbrough.
He said: “Make no mistake, we are on course for a Labour majority at the next general election.”
Meanwhile, Rishi Sunak admitted he was “disappointed” but insisted it was “hard to draw firm conclusions” from the initial results, with a little over a quarter of councils having declared.
The Prime Minister said the Tories are “making progress in key electoral battlegrounds like Peterborough, Bassetlaw, Sandwell”.
He added: “I am not detecting any massive groundswell of movement towards the Labour Party or excitement for their agenda.”
The Conservatives suffered losses in the North, South and Midlands as the prospect of a general election in 2024 looms, while Labour have seized battlegrounds.
