Pevensey is a village and civil parish in the Wealden district of East Sussex, England. The main village is located five miles (8 km) north-east of Eastbourne, one mile (1.6 km) inland from Pevensey Bay. The settlement of Pevensey Bay forms part of the parish. It was here that William the Conqueror made the landing in his invasion of England in 1066 after crossing the English Channel from Normandy.
Ordnance Survey places 124 postcodes in Pevensey Bay 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 1,943 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 32 | 179 | 136 |
| Medium | 2 | 25 | 24 |
| Low | 34 | 552 | 536 |
| Very low | 56 | 1,187 | 825 |
| All bands | 124 | 1,943 | 1,521 |
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.
…and 24 more at-risk postcodes, listed on the district pages below.

The nearest watercourse on the river map is Salt Haven, about 100 m from the middle of Pevensey Bay's gauges.
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 Salt Haven nearest the middle of Pevensey Bay's gauges. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
