Does BA16 0NZ flood?

Up to Medium likelihood

Properties in BA16 0NZ sit in the Environment Agency's Medium 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 medium-likelihood area has a 22–57% chance of flooding at least once.

How much rain falls on BA16 0NZ

BA16 0NZ gets about 773 mm of rain a year on average (wettest month October, 86 mm; driest March, 49 mm). That is 34% 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.
