Thanks to a natural phenomena, known as the 19-year astronomical cycle there will be a number of exceptionally high tides over the next few months.

And conversely, an unusually high tide is followed by an exceptionally low one.

Weather conditions will continue to play a dominant role in whether tides meet predictions, so the guidance from the Port of London Authority, is just that, a guidance.

But, the dates for super tides, should you want to see more than usual amounts of riverside foreshore — or very much less of it — are:


27th Sept (highest 1pm, lowest 7:10am/8pm) <- Thames Barrier Annual Closure

28th Sept (highest 1:43pm, lowest 8:10am/8:50pm)

29th Sept (highest 2:30pm, lowest 9:50am/10:20pm)


27th Oct (highest 1:20pm, lowest 7:45am/8:25pm)

28th Oct (highest 2pm, lowest 8:40am/9:10pm)

29th Oct (highest 2:45pm, lowest 9:20am, 9:50pm)

30th Oct (highest 3:30pm, lowest 10am/10:30pm)


25th Dec (highest 1:30pm, lowest 7:50am/8:20pm)

26th Dec (highest 2:15pm, lowest 8:45am/9pm)

27th Dec (highest 3pm, lowest 9:30am, 9:40pm)

January 2016

11th Jan (highest 2:50pm, lowest 9:10am, 9:20pm)

12th Jan (highest 3:30pm, lowest 10am, 10pm)

13th Jan (highest 4:15pm, lowest 10:40am, 10:45pm)

14th Jan (highest 5pm, lowest 11:20am)


(Excepting the small hours, and based on London Bridge — times will vary a little depending on where you are. Rounded to the nearest sensible time)

This website has been running now for over a decade, and while advertising revenue contributes to funding the website, it doesn't cover the costs. That is why I have set up a facility with DonorBox where you can contribute to the costs of the website and time invested in writing and research for the news articles.

It's very similar to the way The Guardian and many smaller websites are now seeking to generate an income in the face of rising costs and declining advertising.

Whether it's a one-off donation or a regular giver, every additional support goes a long way to covering the running costs of this website, and keeping you regularly topped up doses of Londony news and facts.

  1. The September 27th super-low tide coincides with the annual Thames Barrier Closure.
    Underspill begins at super-high tide around 1pm.

  2. So sad that your picture features a corner of the Greenwich river bank now disappeared. The silos of the food processing plant that once stoon on this place now gone.

    Soon it will have to be explained to children that there was once great industry on the river. That there was a time before over-priced, undersized glass and chrome shoe boxes: 🙁

      Indeed. Greenwich peninsula is set to be blighted by more of these horrors, and some of the older buildings are looking distinctly down as heel with stained or cracked rendering and a general air of decay.

      Back to the subject, though. There have been several very high tides affecting Greenwich this year with the water splashing over riverfront walkways.
