The map of Aberystwyth’s gauges and flood maps loads as you reach it.

Flood Zones, Warning Areas and Surface Water are Environment Agency maps and cover England only. Aberystwyth is in Wales, so they draw little or nothing here — that is where the map ends, not an absence of flood risk. Natural Resources Wales’s warning areas have their own pages under flood areas.

The watercourse nearest Aberystwyth

The nearest watercourse on the river map is Afon Rheidol (tidal here), about 30 m from the middle of Aberystwyth's gauges.

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 Afon Rheidol nearest the middle of Aberystwyth's gauges. 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.

Flood Monitoring in Aberystwyth

Aberystwyth is monitored by 1 Natural Resources Wales river level station on the Afon Rheidol, in Ceredigion. Water levels are updated every 15 minutes, providing real-time flood monitoring for the area.

Monitoring Stations

The Afon Rheidol is monitored by 1 station (Aberystwyth TideGauge). Each station records water levels continuously, with data synced to FloodRadar every 5 minutes.

Environment Agency Flood Warning Areas

No Environment Agency flood warning area is mapped within 10km of Aberystwyth. That means the EA has not defined a warning target area here, which is not evidence the town cannot flood: warning areas exist where the EA runs a warning service, and surface-water and groundwater flooding have no warning areas at all. The EA’s register covers England only — Aberystwyth is in Wales, where the warning service is Natural Resources Wales’s, and FloodRadar publishes its areas alongside the EA’s on the flood areas index.

Sewage Discharge Monitoring

There are 10 storm overflows within 5km of Aberystwyth. None of the 10 with a reporting monitor are currently discharging. Enable "Sewage" on the map above to see their locations.

Recorded floods near Aberystwyth

No recorded flood outline within ~5 km of the Aberystwyth town centre means no flood was mapped here, which is not evidence none happened: the Environment Agency mapped only some floods, mapping effort rose sharply after about 2000, and surface-water flooding is largely absent from this record. The Environment Agency's Recorded Flood Outlines cover England only, and Aberystwyth is in Wales — so an empty record here is an absence of coverage, not an absence of floods.
