Extreme Caution – EBB TIDE Very Strong Fluvial Flows

Fluvial flows are very strong. Conditions are difficult and dangerous. All man-powered vessels are advised not to go afloat on the ebb tide.

Caution – EBB TIDE Strong Fluvial Flows

All river users of man-powered vessels should navigate with extreme caution and consider whether it is safe for them to go afloat on the ebb tide. PLA advise man-powered vessels - in particular schools, novices, junior crews - or those that do not usually use the tidal Thames not to go afloat on the ebb tide.

Average Fluvial Flows

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

Caution - Low Fluvial Flows

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