Maesteg is a town and community in Bridgend County Borough, Wales. Maesteg lies at the northernmost end of the Llynfi Valley, close to the border with Neath Port Talbot. In 2011, Maesteg had a population of 20,612. The English translation of Maesteg is 'fair field'.
Flood Zones, Warning Areas and Surface Water are Environment Agency maps and cover England only. Maesteg 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.
Maesteg is monitored by 1 Environment Agency river level station on the Llynfi, in Bridgend. Water levels are updated every 15 minutes, providing real-time flood monitoring for the area.
The Llynfi is monitored by 1 station (Maesteg River Station). Each station records water levels continuously, with data synced to FloodRadar every 5 minutes.
No Environment Agency flood warning area is mapped within 10km of Maesteg. 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 — Maesteg 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.
If flooding is forecast in Maesteg, call Floodline on 0345 988 1188 for the latest information. Move valuables upstairs, turn off gas and electricity if safe to do so, and avoid walking or driving through flood water. Sign up for flood warnings on any station page above to receive email alerts when water levels rise. For emergency numbers, a preparation checklist and insurance guidance, see our flood help & preparation guide.
Maesteg gets about 2,244 mm of rain a year on average (wettest month December, 262 mm; driest April, 128 mm). That is 93% wetter than the UK as a whole, which averages 1,163 mm a year. See the rain gauges →

No recorded flood outline within ~5 km of the Maesteg 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 Maesteg is in Wales — so an empty record here is an absence of coverage, not an absence of floods.
