- The Mersey bore starts somewhere behind John Lennon airport. It travels all the way (disappearing in some stretches of the river) to the Howley Weir in Warrington, where it meets its end.
The first part of the video was filmed from the riverside footpath near Apley Road, between Warrington Bridge and the railway bridge. The bore came into view as it passed under Park Boulevard bridge. It then passed under the railway bridge and become very undular before passing under Warrington bridge and being forced into a sharp right hand bend. As usual, the river and bore look smaller on video than they actually are.
The second part of the video was filmed a month earlier from Knutsford Road (A5061). It was difficult holding the camera steady above the wavy metal fence that runs besides the river. The bore came into view having just passed under Warrington bridge roundabout. It then passed behind the Riverside Retail Park and almost disappeared. The side of the bore by the road became a loud breaking wave as it passed me, then hit a curved wall. There is a sand bank hidden beneath the river by the curved wall which probably contributed to it becoming a breaking wave. As can be seen, the wave was then deflected by the concave curve and became quite complicated. Wave reinforcement happened and a breaking wave was produced that travelled back towards me. An amazing site to see.
The part of the river near the front of the weir is deep and the bore disappeared before it could reach the weir. It took just twenty minutes for the river to rise and top the weir, causing the river behind the weir to start flowing backwards.
Dates filmed: 22nd February (near the weir) and 22nd March (near Apley Rd), 2019
Expected high tides at Liverpool Gladstone Dock: 10.1m/10.1m @ 13:04/12:00
The bore passed the filming location near Arpley Rd at 11:46 (14min before HT at Gladstone Dock)
The bore reached Howley Weir at 1:02 (2min before HT at Gladstone Dock)
Note: the time taken for the bore to reach the weir from near the Apley Rd viewing location was actually only about 4-5mins. The difference is bigger (12mins) from the above timings as they were taken from bores on different dates.

That takes me back. When I was a kid, the Mersey was brown soup, smelt of oil, and had detergent foam on top. *Nothing* lived apart from rats. When it was windy, the foam blew off and chased people up Bridge Street like tumbleweed. It looks like the Garden of Eden now compared to the late '60s. Mr Cormorant knows a thing or two about fishing. 🙂
Just finished watching ferry on the Mersey, 🌉 and wanted to see what it looked like, very calming, so appreciated, thank you!! 🌊
I have lived in Howley for 36 years and have only witnessed this once and believe me, it was a sight to behold (and hear !).
Marvellously captured 👌 🌟 Howley Weir 😮 Thank you 👍
Thanks for posting this, it helped with my classes on renewable energy.
If you know whats going on there , you dont need renewable classes you should be giving them , i do , so simple no one gets it
Have seen Howley weir disappear several times as the incoming tide actually pushes over it. Never seen the tidal bore though. Great video. 👍👍
Never fails to amazing me.....seen it lots of times....had the times down to the minute....amazing 1 second the flow of the river is out toward the sea....in a flash its the opposite way.
Rob the bore on the day you filmed this....was it a big tide....I have seen several 10.3mts tide runs at Runcorn....quite amazing.
Canoed from Howley to Widnes several times....the river is most interesting.
Time and tide and all that.
Nick from Runcorn.
Hi Nick, the tide was 10.1m at Liverpool Gladstone Dock - details on the accompanying text for the video.
That was incredible.
100x as brilliant as i thought it would be.
That goes for both vids.
🙌🏻
Well thank you Bob. :- )
Thanks for posting that, I didn't even know that the Mersey had a tidal bore. It's a shame there are no surfers using it!
Even Kelly Slater couldn't ride that . There's no height and no speed.
Are you kidding?
That was amazing! Seeing the weir disappear was more than I expected. Very interesting.
Well you live and learn! I had no idea this happened on the mersey.
I live near the Shubenacadie River in Nova Scotia Canada and we get to see this twice a day and sometimes you can surf the tidal bore.
Thankyou, that was very interesting!
Great video!
Fascinating thanks for filming it
that was one hell of a sexy wave.
This is why Springsteen always sings about the Mersey Shore
The Trent has the same (the wave itself is known as the 'Aegir') and the really big ones draw in quite a crowd of spectators. Best views are north of Morton near Gainsborough where the river has a long straight run, the bend at Morton takes a bit of a toll on it but it does pick up to an extent by the time it reaches the town itself. Not many decent(ish) uploads on youtube as they tend to be filmed at Gainsborough by folk who can't stop swinging an old camera phone around but it does lead to realistic sea sickness if nothing else.
Very interesting! It's amazing how far inland so much water can travel.
I believe you are confusing the forward movement of a wave with the forward movement of water. Waves move water, mostly up and down. From the beginning to the end of the video there will actually have been very little horizontal water movement, at least, nothing compared to the velocity of the wave.
@@TribusMontibus True. I phrased that poorly.
@@TribusMontibus Hi, I think you may be confusing a bore wave with a sea (or ocean) wave; the sort that crashes onto a beach. You're right in that the sea wave mostly transfers energy rather than forward movement of water. A bore wave is very different. It is the front face of a very large volume of water moving inland, up a river. From the beginning of the video to the end, a very large amount of water has come in, behind the bore wave, and raised the level of the river so much that it topped the weir.
This same event occures Near Moncton New Brunswick Canada The tidal bore in Moncton is caused when the unparalleled tides of 38 feet in the Bay of Fundy begin to make their way up the historic Petitcodiac River. ... Twice daily, observers can watch the tidal bore as this incoming rush of water overtakes the outgoing tide in the formerly placid river.
Howley Weir was actually stop this phenemenon making the mersey onlyl to here so the manny ship could not be tide-dependant....dun't work ver well, does it? woolston eyes will cop the lot! great video by the way love the cormorannt
I thought the Mersey Bore was a Harry Enfield character.
Amazed It was -great video⭐⭐⭐⭐⭐
I agree Yoda
Excellent stuff.
Thanks for your videos. It's so different from my region in New Plymouth NZ. Do you have any videos of what it's like where the sea comes in to the estuary and the change from normal sea to tidal bore?
Thanks for your comment Lyn. I’m afraid there are no tidal bores in NZ. Where a tidal bore wave first appears in a given river estuary is not so easy to predict. It depends on many things such as the rate of river flow out to sea, the size of the incoming tide, atmospheric pressure, the shape of the river bed, wind strength and direction etc. The closest I have come to filming the ‘birth’ of a bore was on the river Wyre in the UK, on 29 October 2015 (on RUclips). Usually you can see the tidal front making its way across sandbanks or against the river bank, but it doesn’t become a tidal bore until a wave is produced on the river or on the river channel in the estuary. The wave can be smooth (undular) or breaking/rolling and is not very high to begin with.
Nice vide
Ever fresh mersey.
Extraordinary: I never knew the Mersey had a bore. Thanks.
I didn't realise the mersey had a tidal bore. I know the Severn does but not this river.
Why does the Thames not have a tidal bore? I assume it is because of the Thames Barrier which would stop it from forming.
Wow that was awesome to see, thank you. I just learnt yesterday also about the strid on the river wharfe in Yorkshire that it's claimed to be the most dangerous in the world.
Try and find tge strid explore video on y.t

Youre welcome
👌
Oh right interesting fantastic Warrington
Those waves look like waves I made in the bathtub when I was five years old. A little less than epic.
Interesting. How far from airport to the Weir ? Curious side bounce at the Weir !
Hi Antony. Liverpool airport is about 13 miles from the weir... in a straight line. The path the river takes will be quite a bit longer than that. As the river approaches the weir it turns 90 degrees left on a wide almost angular corner. I’ve watched the bore arrive here a few times and it always performs the same strange bounce sequence. The Mersey bore is a good one to chase as there are many good viewing locations along its path.
Usually tides come in so slow u can hardly notice them. How come this area it comes in so fast kind of strange. But theres been stranger things oh well
Amazing!
This phenomenon is called marrobbio in Italian and it happens wrapped Mazara del vallo in Sicily there are videos present on RUclips the important thing is that it has not created any damage
Hi Anna. The marrobbio that occurred in June 2014 at Mazara del Vallo was a one-off event caused by very unusual atmospheric disturbances off the coast of Sicily. It was what is called a meteotsunami. What you see here on the river Mersey is a tidal bore, which is very different. A tidal bore is essentially the tide coming in with great force, so much so that it overwhelms the outgoing river flow and causes a wave to be produced that travels up the river. Tidal bores can be predicted by using tide times and river levels and during periods of high spring tides, they can occur up to twice a day, roughly 11.5 hours apart.
Thanks for letting me know about the marribio at Mazara del Vallo; the videos of it are very impressive.
Tidal shores are so weird. What if there's a meander in the river? Does it follow the curve?
They can become a bit messy on curves, but usually they do follow the curve with the wave moving faster on the longer stretch.
I was laughing like crazy when I saw that bird with his wings out, like its saying : There's nothing to see here now get out of here!!!
A shag drying it’s wings.
Anyone try surfing that? If it gets a little shallower in the mid river area might ramp up a bit better like it does on the banks
Who needs love island?
I dont know about these days, but by god it used to stink round Howley Weir!
As you can see by the wild life, its clean. No idea how far back you are going!!
@@emmsue1053 I am thinking of 60 or more years ago. If you think back about some of the industries that were discharging into rivers, but are no longer doing so for example tanneries, that, added to the efforts that have been made to clean up waterways, things should be much better. I haven't been "riverside" in Warrington for many years so I cannot personally compare like with like aroma wise. There were stuffed creatures in Warrington Museum that had swum up the Mersey many years ago, it would be interesting to know what aquatic life appears now. My cousin's son I believe has won fishing matches in the river, so I assume it it clean enough.
Not any more. There are fish, cormorants, kingfishers, loads of ducks and there have been seals and otters over the years too. Lots of lovely wildlife round here which is a joy to witness.
This is actually footage of a Loch Ness Monster like creature swimming underwater.
How long does it take to cover the weir?
About 20 minutes on a high spring tide.
@@robbridges5975 faster then I was thinking.
Very impressive there i think.
WOOOOW !
Wow really I live right next to this damn river
Great video pal is this daily occurring At high tide? Looks much healthier than it used to.👍😎
Superderm. The bore at this location will only occur under certain circumstances... the river mustn’t be swollen after heavy rain and the high tide at Liverpool Gladstone dock is over 9.5 meters. Even then it can be temperamental whether it will show or not. If conditions are right then the bore will reach this location in Warrington about 10-20 minutes before high tide at a Liverpool Gladstone dock. Hope you get to see it some time, it looks and sounds much more impressive in reality than it does on video.
I didn't make this joke but...
"When the tide is late."
So Mary, cross the Mersey...............
Amazing the audacity of that man to steal a police car.
I would love to swim in that
Is it deep?
Will891410 Yes, the river runs deep here. If it were more shallow the bore would be much more dramatic and form a breaking wave.
@@robbridges5975 I mean, i would not say its deep, visual can be very deceiving.
@@robbridges5975 how deep on average, do you think?
@@robbridges5975 yeah we're all still waiting with bated breath if you do know how deep it is or not it's okay we'll find out
@@allenpeck8239 I really don’t have the info you are seeking Allen. If one day you hire a boat, travel up the Mersey and take depth readings along the way with a weight a string (to get an average figure), then I’d be interested to hear of your results.
'
how the water wave come from
It is the tide coming in.
@@robbridges5975
hi R B...
'
yes right but where tide come from...
boat or ship / mini earthquake / wind
or the moon control water on the earth
@@bestamerica en.wikipedia.org/wiki/Tidal_bore
Not bad have seen a lot better though.. more so in Chine ..
Thanks for your contribution Brian, though I didn’t realise my video was in some sort of ‘I’ve seen better’ competition. Perhaps you can post your video of the better bore you’ve seen?
@@robbridges5975 Precisely... lol
It was a GREAT vid !
