Big Tides

The Bristol Channel has the second-largest tidal range on Earth. South Gower spring tides range some 10 m between low and high water, while tides in the Loughor Estuary range somewhat less. Natural changes according to the orbits of our heavenly neighbours and to seasonal weather systems can cause significant variations.

Big spring tides here are always around 7-8 am and, of course, 12 hrs 25 mins later
North Gower marsh ponies commonly stand-out the high tides; salt-marsh sheep don’t!

It reads ‘No road markings’!

Low spring tide rock platforms are locally several hundreds of metres wide, normally unseen
Estuary out-going tide against the “Slags” training wall runs about 1 metre above the sand on the outside.
Viewed along the “Slags” back towards Penclawdd, the upstream water is clearly about 1 m above that on the right.
