Thames tide FAQ

Is this a tide prediction?

No. This page shows observed Environment Agency tide gauge readings. It is useful for the current tide level and recent movement, not as a future tide table.

How often is the Thames tide data updated?

The Environment Agency API normally updates tide gauge readings every 15 minutes, and the latest available reading usually lags by 15 to 30 minutes.

Which station should I use for central London?

Tower Pier is the best default for central London because it is close to Tower Bridge and the Pool of London.

Can I use this for boating or safety decisions?

No. Treat this as a public information tool only. For navigation, flood risk or safety decisions, use official navigation and flood warning sources.
