Up to Medium likelihood
Properties in YO7 3EL sit in the Environment Agency's Medium 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% | 0 | 0 |
| Medium | 1% – 3.3% | 3 | 3 |
| Low | 0.1% – 1% | 17 | 16 |
| Very low | below 0.1% | 0 | 0 |
Over a 25-year mortgage, a property in a medium-likelihood area has a 22–57% chance of flooding at least once.
YO7 3EL gets about 644 mm of rain a year on average (wettest month August, 68 mm; driest March, 39 mm). That is 45% 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 ground here sits at about 23 m above sea level and falls 5 m across the surrounding 800 m. Surface water reaching this point runs off ground lying to the south-east, 4.6 m higher.
The river map has no watercourse within 1 km of the centre of YO7 3EL.
That means this spot is not on the river map, not that there is no water here: Ordnance Survey’s river map (OS Open Rivers) leaves out small streams, ditches and culverts. Contains OS data © Crown copyright and database rights 2026.

The map above shows the real EA rivers & sea likelihood cells around YO7 3EL. The small panels are illustrative previews of the report's per-layer map views — the full report draws each layer for real, plus recorded extents, defences and a building picker on an interactive map.
Warnings cover flood areas, not individual addresses.
| Date | Mapped flood extent | Approx. distance |
|---|---|---|
| Jan 2021 | 2021 January Flood Incident - Storm Christoph | ~44.9 km |
| Feb 2020 | 2020 February Flood Incident - Storm Dennis | ~11.1 km |
| Feb 2020 | 2020 February Flood Incident - Storm Ciara | ~20.2 km |
| Nov 2019 | 2019 November Flood Incident | ~72.7 km |
These are extents the Environment Agency has mapped, not a list of every flood. Records, not floods: no outline on the record is not evidence a place has not flooded. The full report tests whether any extent covered the exact spot.
