Coastal Erosion and Monsoon Rain Threaten Ullal, Karnataka
Coastal Erosion and Monsoon Rain Threaten Ullal, Karnataka
IN · Published Sep 15, 2026
Ullal, a coastal town in Karnataka, is experiencing the effects of the intense southwest monsoon, which brings heavy rain and rough Arabian Sea swells. The town has been significantly impacted by coastal erosion, losing an average of 1.3 metres of land annually since
A hyperlocal radar system, updated every 5 minutes by RainViewer using India Meteorological Department (IMD) data, shows a weather system building off Ullal's shoreline. While nearby Mangaluru remains unaffected, Ullal faces the dual threat of heavy rain and wind-driven waves, which exacerbate the erosion and damage the coastline.

Impact & Risks

The primary risk in Ullal is coastal erosion rather than inland flooding. The combination of heavy monsoon rain and wind-driven waves accelerates shoreline damage, making Ullal more vulnerable than other towns along the Karnataka coast. Travel on NH66, which passes through Ullal, may also be disrupted due to heavy rain. Residents and visitors are advised to monitor the live radar closely, as Arabian Sea monsoon cells can intensify rapidly, posing risks to coastal activities and infrastructure.
