Whether you're joining our waterways or leaving for the Thames, there's important things you need to know. The tidal locks to the Thames are Thames Lock Brentford, Limehouse, Bow and West India Dock Entrance.
Boating on the tidal Thames presents a unique set of challenges. For instance, it's not uncommon for the passage between Teddington and Limehouse to have waves over a metre tall with tidal flows in excess of four knots. But for the experienced boater it's well worth a go.
The River Thames flows down stream towards our Docklands office.
But the tide is more powerful - it'll be either pushing water back up towards Teddington. Or puling it back towards the Docklands. If you're travelling on the Thames, you need to travel with the tide.
High tide (or hogh water) is the point at which the tide's direction switches. You'll want to be at your destination by then!
Boats travelling from Teddington to Brentford:
The usual advice is to lock into Teddington about 45 minutes after high water at London Bridge (about 45 minutes to Brentford)
Boats travelling from Brentford to Teddington:
The usual advice is to lock into Brentford about 60 to 90 minutes before high water at London Bridge (about 45 minutes to Brentford)
Boats travelling from Brentford to Limehouse:
The usual advice is to lock into Brentford about one hour after high water at London Bridge
Boats travelling from Limehouse to Brentford:
At this point ask yourself 'what time are you leaving Limehouse?'. Your arrival in Brentford will be about two and a half hours after that
So, using the tidal locks therefore depends on the tide. However, you can only use the tidal locks at Thames Lock Brentford, Limehouse, Bow and West India Dock Entrance when our team or volunteers are on site.
When booking a lock, you may need to leave a message on an answering machine. Please ensure you explain:
You can view lock closures on the stoppage pages of our website.
