Southampton Flood Map
Map of Southampton (Hampshire) postcodes and their flood risks. Each postcode is assigned a risk of high, medium, low, or very low, and then plotted on a Southampton flood map. Most Southampton postcodes are high flood risk, with some medium, and low flood risk postcodes.
Status:
High
Medium
Low
Very Low
IMPORTANT: We have taken a single point within a Southampton postcode using Open Postcode Geo and identified the flood risk area which that point falls within. There maybe other points within the postcode which fall into a different area, and hence have a different risk level.
