Kuala Lumpur enjoys year round equatorial climate which is warm and sunny, along with plentiful rainfall, especially during the southwest monsoon from April to September. Due to the close proximity of Kuala Lumpur to the Sumatra Island, dust particles are carried by wind from frequent forest fires, creating a phenomenon known as the haze. This usually lasts for 1 to 2 weeks.
