Images flooded onto social media after the high tide saw water break over the river’s banks in some places.
The Thames Barrier was closed to protect London from the “high tide of the centre” as a “supermoon” linked to yesterday’s (admittedly underwhelming) partial solar eclipse caused rising water levels.
High tides were seen in Greenwich, Putney Embankment, Chiswick Mall and Strand-on-the Green, the Evening Standard reported.

London was not the only place affected.
A supertide enveloped France's famous Mont Saint-Michel, briefly cutting it off from the mainland before retreating back.

Hailed as ‘the tide of the century’ (despite happening every 18 years), the tide drew in thousands of tourists at the Unesco world heritage site, which is normally linked to mainland Normandy only by a narrow causeway at high tide.
The high tide, said to rise at the pace of a horse's gallop, turned the Mont briefly into an island today, while the day's low tide allowed people to walk on the expansive flat seabed.

Forecasters predicted the tide could reach as high as 14 metres, but tidal expert Nicolas Pouvreau told France 24 waves fell a few inches short of what was expected.
An even higher tide has been forecast for Saturday night.
