Does BN22 7QW flood?

Eastbourne, East Sussex

Up to Very low likelihood

Properties in BN22 7QW sit in the Environment Agency's Very low flood-likelihood band (worst property). The band is the worst found in the postcode — it describes the land around properties (defence-adjusted, rivers & sea), not any single address, and not today's conditions.

Over a 25-year mortgage, a property in a very low-likelihood area has less than a 3% chance of flooding at least once.

How much rain falls on BN22 7QW

BN22 7QW gets about 797 mm of rain a year on average (wettest month December, 101 mm; driest April, 45 mm). That is 31% drier than the UK as a whole, which averages 1,163 mm a year.

A thirty-year average for the surrounding area, not a measurement at this address and not a flood risk on its own: a dry area floods when a storm sits over it, and a wet one may drain away perfectly well.
