Summary of Highest Tides, Chiswick Mall, 2023
This page is a quick guide to this year’s highest tides on and around Chiswick Mall. Parts of the roadway in Chiswick Mall are often flooded, as the main flood defence is along the building line, leaving the road unprotected. Flooding of property, as distinct from front gardens and the roadway, is not normally expected. A flood alert or warning would be issued if property was threatened.
As well as the "London Bridge" tide heights which most Thames tide tables include, I also show the predicted height in metres Above Ordnance Datum (mAOD) on Chiswick Mall which enables a comparison with local land heights. For more information about AOD heights, see the AOD page.
Below are three tables:
- Table 1 shows the dates on which some flooding of the road is likely (predicted tide level of at least 4.0 mAOD at Chiswick Mall).
- Table 2 gives more details of the highest tides (predicted level of at least 4.3 mAOD) when more extensive flooding of the roadway can be expected. Tides predicted to reach at least 4.5 mAOD are shown in bold.
- Table 3 lists the known AOD land heights on or near Chiswick Mall.

Table 2: Details of highest tides when extensive flooding of Chiswick Mall is likely
The table below lists all the tides in Chiswick Mall up to December 2023 that are predicted to be 4.3m AOD or higher. Tide times are for the peak of the tide at Chiswick Mall (junction with Chiswick Lane South, at the upstream end of Chiswick Eyot) in local clock time - GMT or BST according to season. These times and heights are predictions only, and in practice may be influenced by actual river flow and the weather.
