Does SS3 9DA flood?

Shoeburyness, Southend-on-Sea

Up to Low likelihood

Properties in SS3 9DA sit in the Environment Agency's 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.

Likelihood bandAnnual chancePropertiesOf which homes
Highgreater than 3.3%00
Medium1% – 3.3%00
Low0.1% – 1%1110
Very lowbelow 0.1%116

Over a 25-year mortgage, a property in a low-likelihood area has a 2–22% chance of flooding at least once.

How much rain falls on SS3 9DA

SS3 9DA gets about 534 mm of rain a year on average (wettest month October, 57 mm; driest March, 34 mm). That is 54% 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.
