KUALA LUMPUR: The phenomenon of large waves at several locations in Penang and Pulau Pangkor, Perak, is unusual, said the Malaysian Meteorological Department (MetMalaysia) director-general Dr Mohd Hisham Mohd Anip.
He said such natural incidents occur due to the simultaneous presence of the high tide phenomenon brought about by the perigee condition or the moon's close proximity to the earth as well as the full moon and strong westerly winds.
