Does Wimbledon flood?
What the Environment Agency's rivers-and-sea flood-risk data says about Wimbledon
Ordnance Survey places 48 postcodes in Wimbledon in the Environment Agency's rivers-and-sea flood-risk dataset (Risk of Flooding from Rivers and Sea). Each postcode is counted once, under the worst band any of its properties reaches; together they hold 1,146 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 10 | 217 | 165 |
| Medium | 24 | 452 | 414 |
| Low | 14 | 464 | 414 |
| Very low | 0 | 13 | 9 |
| All bands | 48 | 1,146 | 1,002 |
This dataset covers flooding from rivers and the sea only — one of five flood sources. Surface water, groundwater, sewers and reservoirs are assessed separately, so a postcode missing from it is not proof that a place cannot flood. The band describes the land around properties (allowing for defences), not any single address and not today's conditions.

A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on the River Wandle nearest the middle of Wimbledon's at-risk postcodes. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist.
