Cleveleys found itself in the national spotlight over the festive period – thanks to its seasonal, white-coated promenade.
But it wasn’t snow which covered the seafront but a thick layer of white, oily bubbly foam.
The amazing phenomenon even has boffins scratching their heads. It is thought to be the result of decomposing algae matter but scientists are still investigating.
Gallons of the sea foam carpeted the whole of Princess Promenade, at the Anchorsholme end of town, with the thick layer of oily bubbles.
Residents weren’t too happy with it, though. Gordon Stanley, of Rossall Promenade, said: “The situation with the foam is horrendous, normally it happens once every few years but it has been like this three times this year.
It is oil based so it is terrible for your car and stains your clothes.”
An Environment Agency spokeswoman said: “We have taken samples as if this is caused by polluting material, we need to know about it.
“Early samples are not showing any trace of detergent so we think it could be the combination of decomposing algal matter churned with the tide.”
