Yes, in places, and the places are not a secret. The village sits on flat ground where a stream spreads out before it reaches the estuary. Roughly one postcode in seven sits in the highest river and sea flood zone. The most recent recorded flood here happened when defences were overtopped. Braunton does not have a flooding rumour. It has a flooding map, and the map has streets on it.
The Environment Agency's river and sea mapping puts about 14% of Braunton's postcodes inside flood zone 3, the highest-probability band, and about 3% inside flood zone 2. Zone 2 being the smaller figure trips people up every time. It is the extra medium-probability fringe lying beyond zone 3, not a wider circle drawn around it, so the two are separate bands rather than one containing the other.
Surface water is not published here as a share of its own. It sits folded into the combined postcode indicators further down, which matters when comparing this village against anywhere else that reports the two separately. What is specific is the record: ten flood events logged for the area, the most recent in December 2012, when a main river came over its defences. About 4% of postcodes fall inside the historic flood extent. Braunton Marsh has its own drainage board covering about 1% of postcodes, which is the kind of institution that only exists where water needs managing rather than admiring.
Apply the Environment Agency's climate change allowance and the zone grows to about 21% of postcodes. That is the same map with the future switched on, and it is a larger map than the present-day one.
For insurance, this is the difference between a purchase and a project. A property inside zone 3, or inside the climate extent, is a conversation with an underwriter rather than a box on a comparison site, and the answer varies street by street rather than village by village. Getting an indicative quote on the exact address before instructing a solicitor is cheaper than finding out afterwards.
Taking all the flood indicators together, including surface water, about 18% of Braunton's postcodes rate high on at least one measure, about 13% medium and about 31% low. Those bands overlap the flood zone figures rather than stacking on top of them, so nothing here should be added together.
Counted as homes rather than postcodes, the Environment Agency's rivers and sea mapping lists 1,437 properties across the 66 postcodes that carry any risk at all. Of those, 319 sit at high risk, 97 at medium and 305 at low. Of the high-risk properties, 208 are residential. Postcodes with no risk never appear in that list, so this is the affected part of the village described in full rather than the village averaged out.
On whether anything stands in the way, about 15% of postcodes sit inside the high-risk modelled extent with no defence present in the model, against about 13% where a defence is present. The word defended does a lot of quiet work there. It means the model knows a structure exists, not that the structure is maintained, not that it is high enough, and certainly not that the house behind it is safe.
The coast is close. About 12% of postcodes sit within 500 metres of it, which is the threshold the mapping uses rather than a statement about any one address. The nearest point of the place is about 130 metres from the water, while the median postcode sits about 930 metres back.
Every postcode here falls under a shoreline management plan. The stated policy is to hold the line over the next twenty years, managed realignment over fifty, and holding the line again over a hundred. Read that sequence slowly: the fifty-year intention is to let the water take ground and defend a different line afterwards. A policy is a stated intention to maintain defences over a horizon, not a defence that already exists and not a promise that anyone funds it.
The nearest long-record tide gauge is at Devonport, where sea level rose by 2.35 millimetres a year across the 1962 to 2015 record. That is measured history rather than a projection.
Flooding is the weakest part of the case for living in Braunton, and it is the one risk here that will not improve on its own. The village is entirely liveable, but the address matters more than the postcode, and the postcode matters more than the map at the top of the estate agent's window.
