Does TN36 4LU flood?

Up to High likelihood

Properties in TN36 4LU sit in the Environment Agency's High 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 band	Annual chance	Properties	Of which homes
High	greater than 3.3%	4	2
Medium	1% – 3.3%	0	0
Low	0.1% – 1%	0	0
Very low	below 0.1%	24	18

Over a 25-year mortgage, a property in a high-likelihood area has at least a 57% chance of flooding at least once.

How much rain falls on TN36 4LU

TN36 4LU gets about 764 mm of rain a year on average (wettest month November, 95 mm; driest March, 44 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.
