The chain announced last year that it would be selling nearly 40 of its pubs due to the combined impact of the pandemic and soaring prices.
It said more closures would be on the cards in November after sales dropped 1.1 per cent.
So far, 11 of the pubs have been sold off, with them gradually closing their doors for good.
Some of the venues closing include Moon on the Square in Basildon and Wild Rose in Bootle.
But boss Tim Martin said he remained “cautiously optimistic” about Wetherspoons’ future.
Mr Martin said: “The aftermath of the pandemic and lockdown restrictions have been far more difficult than anyone thought.
“That is the picture for the whole pub and restaurant industry. People thought that after lockdown there would be a boom in people suffering from cabin fever but, instead, it has almost been the opposite situation as people have got in the habit of staying in.
“That’s the big thing that means sales are down on 2019. Things are improving now but it’s slow.”
Wetherspoon was established in 1979, first opening its doors in north London.
