Does OX29 5AP flood?

Up to High likelihood

Properties in OX29 5AP 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 bandAnnual chancePropertiesOf which homes
Highgreater than 3.3%1770
Medium1% – 3.3%00
Low0.1% – 1%30
Very lowbelow 0.1%00

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 OX29 5AP

OX29 5AP gets about 680 mm of rain a year on average (wettest month November, 71 mm; driest March, 43 mm). That is 42% 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.

The watercourse nearest OX29 5AP

The nearest watercourse on the river map is Westend Brook, about 140 m from the centre of OX29 5AP. It flows into Northmoor New Cut about 760 m downstream.

A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on Westend Brook nearest the centre of OX29 5AP. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
