Monsoons

The end of Aug 2014 was quite wet and Sept started dry and cloudy. The southwest monsoon should just be ending, then it will be hot and dry until the northeast monsoon starts around Nov.

The Southwest Monsoon usually occurs between May till September, bringing rainfall to the western side of Peninsular Malaysia. This affects places such as Kuala Lumpur, Penang and Langkawi and Perlis.
Perak seems to be missed, presumably because of the shape of Sumatra, as the winds are coming 'around' Sumatra.

Perlis - It is generally dry and warm from January to April. Average rainfall per year falls between 2,032 mm to 2,540 mm with the wettest months being from May to December.

The Northeast Monsoon starts from November and lasts till March, brining heavy rainfall to areas on the east side of Peninsular Malaysia, such as Kuantan, and Borneo (Sabah and Sarawak). As this monsoon wind is particularly strong, it often brings heavy rain to the west side of Peninsular Malaysia as well during this period.

The northeast monsoon brings heavy rain and rough seas to the exposed coasts of southwestern Sarawak and northern and northeastern Sabah, and it sometimes causes flooding in the eastern part of the peninsula.

Singapore, 27 October 2014 – Singapore and the surrounding region can expect more rain in the coming weeks, as the Southwest Monsoon has transitioned to Inter-Monsoon conditions over the past week. This signals the end of the traditional dry season in the region, and the likelihood of transboundary haze affecting Singapore for the rest of the year will thus be low.

The Inter-Monsoon period normally lasts from October to November, and is characterised by more
rainfall and light winds that are variable in direction. The increased rainfall will help alleviate the
hotspot and haze situation in Sumatra and Kalimantan. During this period Singapore may experience occasional slight haze, mainly in the morning, on some days due to the accumulation of particulate matter in the air under light wind conditions. The haze situation is expected to improve further with the onset of the rainy season brought by the Northeast Monsoon in early December.
