The erosion stretches across about 13.9 kilometres in Phong Quang, Thuan An, Phu Vinh, Vinh Loc and Phu Loc, according to the city's Department of Agriculture and Environment.
Thuan An Ward is among the areas hardest hit by coastal erosion, particularly during the rainy season from September to December, when strong waves and high tides regularly damage sea defences and other infrastructure.
Climate change has made coastal erosion in the area increasingly severe and unpredictable in recent years, local authorities said.
A VND 260-billion project to protect a 1.4-kilometre stretch of coastline in Thuan An began in June and is scheduled for completion by the end of 2027. The project is aimed at stabilising the shoreline and protecting residents and property.
Heavy rain from September 10 to 13 brought waves of 1.5-3 metres to the area, forcing construction work on the project to be temporarily suspended for safety reasons.
Hue has about 127 kilometres of coastline, which is frequently exposed to erosion caused by strong winds, rough seas, storms, tropical depressions and flooding.
During the 2025 rainy season, erosion along a one-kilometre section of coastline in Thuan An extended 50-70 metres inland, threatening essential infrastructure and tourism facilities.
In Vinh Loc, a two-kilometre stretch was eroded by 10-30 metres, affecting Road 21 and other infrastructure. Coastal erosion also damaged about 400 metres of a road leading to Tan An Hai Village in Phu Loc.
Hue has reinforced more than 10.6 kilometres of coastline with erosion-control structures at a cost of over VND 1.1 trillion.
The city is continuing to monitor high-risk areas and has sought central government funding for further coastal protection and climate adaptation projects.
