Noticed any high tides in the Thames recently? You may be interested to know the reason.

Flood warnings had been placed along the Thames for the beginning of September in Limehouse, Rotherhithe, Greenwich and Three Mill Island in Bow.

While the warnings have temporarily been lifted, it still caused a minor panic – and it’s all down to the “Supermoon”.

On Saturday, August 29 the moon’s gravitational pull was at its strongest due to its proximity to earth.

Tides are governed by the gravitational pull of the moon and, to a lesser extent, the sun. Because the sun and moon go through different alignments, this affects the size of the tides.

When the gravitational pull of the sun and moon combine, we see larger than average tides – known as spring tides.

We are currently at the height of those increases, so the astronomical tide is at an 18-year peak – although this is only a few centimetres bigger than a more average spring tide.

An Environment Agency spokeswoman said: “The Environment Agency is monitoring the situation closely alongside the Met Office and local authorities, and will issue further flood alerts and warnings if required. “People should check their flood risk and keep up to date with the latest situation at or follow @EnvAgency and #floodaware on Twitter for the latest flood updates.”

Further “supermoons” are expected on September 28 and October 27.
