The geography of Malaysia deals with the physical and human geography of Malaysia, a country located in Southeast Asia. There are two distinct parts to this country being Peninsular Malaysia to the west and East Malaysia to the east. Peninsular Malaysia is located south of Thailand, north of Singapore and east of the Indonesian island of Sumatra. East Malaysia is located on the island of Borneo and shares borders with Brunei and Indonesia.

Located near the equator, Malaysia's climate is categorised as equatorial, being hot and humid throughout the year. The average rainfall is 250 centimetres (98 in) a year and the average temperature is 27 °C (80.6 °F). The climates of the Peninsula and the East differ, as the climate on the peninsula is directly affected by wind from the mainland, as opposed to the more maritime weather of the East. Malaysia is exposed to the El Nino effect, which reduces rainfall in the dry season.

Malaysia faces two monsoon winds seasons, the Southwest Monsoon from late May to September, and the Northeast Monsoon from November to March. The Northeast Monsoon brings in more rainfall compared to the Southwest Monsoon, originating in China and the north Pacific. The southwest monsoon originates from the deserts of Australia. March and October form transitions between the two monsoons.

Local climates are affected by the presence of mountain ranges throughout Malaysia, and climate can be divided into that of the highlands, the lowlands, and coastal regions. The coasts have a sunny climate, with temperatures ranging between 23 °C (73.4 °F) and 32 °C (89.6 °F), and rainfall ranging from 10 centimetres (4 in) to 30 centimetres (12 in) a month. The lowlands have a similar temperature, but follow a more distinctive rainfall pattern and show very high humidity levels. The highlands are cooler and wetter, and display a greater temperature variation. A large amount of cloud cover is present over the highlands, which have humidity levels that do not fall below 75%.

The highest temperature was recorded at Chuping, Perlis on 9 April 1998 at 40.1 °C (104.2 °F). The lowest temperature was recorded at Cameron Highlands on 1 February 1978 at 7.8 °C (46.0 °F). The highest rainfall recorded in a day was 608 mm (23.9 in) in Kota Bharu, Kelantan on 6 January 1967. The highest rainfall recorded in a year was 5,687 mm (223.9 in) at Sandakan, Sabah in 2006. Meanwhile, the lowest rainfall recorded in a year was 1,151 mm (45.3 in) at Tawau, Sabah in 1997. The wettest place in Malaysia is Kuching, Sarawak with an average rainfall of 4,128 mm (162.5 in) with 247 days of rain a year. The driest place in Malaysia is in Chuping, Perlis with average rainfall of only 1,746 mm (68.7 in) a year.
