The country is made up of two regions. Peninsular Malaysia which lies between Thailand and Singapore, and East Malaysia across the South China Sea on the island of Borneo. The combined land area of both regions is about 330,400 sq km (127,000 sq miles).
Range, known as Banjaran Titiwangsa, which runs from the Malaysia-Thai border in the north to the southern state of Negeri Sembilan. Geographically, East Malaysia is rugged, with a series of mountain range encompassing the interior regions of both states. The Crocker Range in Sabah is the site of Mount Kinabalu, the highest peak in South East Asia. Low's Peak, at 4,093 metres above sea level, is the highest point of the mountain.
The country is generally warm throughout the year with temperatures ranging from 21° to 32° Celsius in the lowlands. This can however be as low as 16° Celsius in the highlands. Annual rainfall is heavy at 2,500mm (100 inches). On a rainy day, thunder and lightning often accompany the heavy downpour which normally lasts for about an hour or two. The high humidity level at 80% throughout the year favours light and sweat-absorbent material like cotton for daily dressing.
Generally, Malaysia has two distinct seasons. The dry season occurs during the south-west monsoon from May and September. The northeast monsoon brings the rainy season to the country during mid-November till March.
