This is a true story I heard of Newquay tsunami waves. The date is unknown to me, but I heard the story in a small pub in about 1999/2000, when it was still fairly recent, so this is a story of the Newquay tsunami wave in about 1999.
A local early morning delivery driver would take a break in his route every morning, on Porth Beach. Porth Beach has a small slipway and a small on-beach car parking area. Each morning, he’d drive onto the beach, park up and get out his newspaper and flask. This morning was no different. The tide was out, nothing unusual going on. Then, from nowhere, a massive tidal surge swept in, lifted his delivery van out and then started pulling it back out into the sea.
This wasn’t a big wave, just enough to pull his van many feet down Porth Beach. He called the rescue services and the police turned up. Of course, they didn’t believe his story, they thought he must be mad, drunk, or on substances. Then, as they were talking to him, another wave did exactly the same thing. They police wouldn’t have believed it if they hadn’t seen it with their own eyes.
This wasn’t a huge tsunami and was probably a tidal surge caused by an underwater landslide between Cornwall and Ireland.
Tidal Surge at Porth, Newquay, 10 March 2008
On 10 March, 2008, there was a huge storm and tidal surge at Porth, Newquay. This tsunami-like wave was caused by a huge 36′ swell and a combination of a fierce storm, wind direction and tidal height. As 2008 was a time when many people had easy access to video cameras, this one was caught on several cameras and uploaded to Youtube.
The tidal surge brought the water level to about halfway up the side of The Mermaid pub, sweeping through the bar, with locals caught unawares and having to prevent the chairs and tables from being swept out to sea.

None of these events were actual tsnuamis, but they do show that tsunami-like events do happen in the area.
