Floods in Malaysia

Floods in Malaysia are regular natural disasters in Malaysia which happen nearly every year especially during the monsoon season. The east coast of peninsular Malaysia is the most prone to flooding especially during the northeast monsoon season from October to March.

Gombak river merges with the Klang river. Heavy development has narrowed certain stretches of the river: this contributes to flash floods in Kuala Lumpur, especially after heavy rain.

Causes
  • Given Malaysia's geographical location, most floods that occur are a natural result of cyclical monsoons during the local tropical wet season that are characterised by heavy and regular rainfall from roughly October to March.
  • Inadequate drainage in many urban areas also enhance the effects of heavy rain, though efforts are underway to resolve this (see below).
  • Floods in Southern Johor was believed to be caused by the Gore Effect. This is because Johor is not within the usual monsoon affected zone.
