When to go to Borneo
Borneo is one of Southeast Asia’s few summer destinations as the best time to travel is between March and October.
The wet season is traditionally from November to February, but the climate in this part of Asia can be very unpredictable so it is best to accept the possibility of rain at any time.
By their very nature, rainforest areas have a wet climate and it is hot and humid for most of the year.
When to go to Malaysia
Kuala Lumpur and the west coast are good destinations all year round but tend to be driest & sunniest between December and March. At any point there is the chance of a short, sharp downpour but these can be welcome as they reduce the humidity.
Unusually for Asia, the east coast is best avoided between November and February when the heaviest rain falls and the sea can be quite choppy. It is at its best with dry sunny days during March to October.
