Ebb tide flag warning

Current river conditions

What the flags mean

Red - Very Strong Fluvial Flows

  • Conditions are difficult and dangerous.
  • All people-powered vessels are advised not to go afloat on the ebb tide.

Yellow - Strong Fluvial Flows

PLA advise people-powered vessels:

  • Beginners, novices, younger junior (J15's and younger), or any weaker crews, and those that do not usually navigate on the tidal section of the River Thames not to go afloat on the ebb tide.
  • All river users of people-powered vessels should navigate with extreme caution and consider whether it is safe for them to go afloat on the ebb tide.

Green - Average Fluvial Flows

  • All river users to navigate with caution and maintain a proper look out.

Black - Low Fluvial Flows

  • Tidal flow is lower than usual. River users should expect lower than predicted tides especially around low water.

How the flag colour is determined

Every day at 6 am and 6 pm the lowest tide reading for the Richmond tide gauge is taken for the preceding 12 hours.

  • If the value is 2.6 metres or above then the flag is RED.
  • If the value is 1.7 metres or above but less than 2.6 metres then the flag is YELLOW.
  • If the value is 0 or above but less than 1.7 metres then the flag is GREEN.
  • If the value is less that 0 then the flag is BLACK.
