What the Environment Agency's rivers-and-sea flood-risk data says about Hythe
Ordnance Survey places 64 postcodes in Hythe 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 668 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 27 | 137 | 69 |
| Medium | 6 | 63 | 21 |
| Low | 21 | 260 | 159 |
| Very low | 10 | 208 | 180 |
| All bands | 64 | 668 | 429 |
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.

The watercourse nearest Hythe
Two mapped watercourses are about the same distance from the middle of Hythe's at-risk postcodes: North Dibden Stream (about 430 m) and Southampton Water (about 550 m), so this page cannot say which one is nearer to you.

Distances along the river are from the point on each watercourse nearest the middle of Hythe'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.
