Does TN36 4AH flood?

Up to Very low likelihood

Properties in TN36 4AH 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.

Likelihood band	Annual chance	Properties
High	greater than 3.3%	0
Medium	1% – 3.3%	0
Low	0.1% – 1%	0
Very low	below 0.1%	1

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 TN36 4AH

TN36 4AH gets about 802 mm of rain a year on average (wettest month November, 100 mm; driest March, 46 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.
