Important! The levels for this location are measured relative to sea level, not relative to the riverbed. The levels shown here do not, therefore, necessarily represent the actual depth of the water.

This is a tidal level, measured from mean sea level rather than from the river bed. It can, therefore, be negative, and does not give any indication of water depth. Tidal levels are not necessarily updated frequently, and may not reflect tidal movements throughout the day.

The usual range of the Thames Tideway at Southend is between -2.53m and 3.25m. It has been between these levels for 90% of the time since monitoring began.

Note: CSV data will include any outlying values that have been ignored by our graphing system as probably erroneous (eg, because they are ridiculously high compared to the values either side of them). It is your responsibility to filter these out if necessary.

Important! If you are planning to retrieve the csv data automatically, you must read and understand the limitations on the data and its availability.
