Remember:
The climate on the island of Sumatra in december ranges from tolerable to bad depending on the region and city.
December is not the best month to spend holidays in Sumatra. The weather in Langsa, Tanjungpinang, Gunung Leuser National Park, Bandar Lampung, Kisaran, Bukit Lawang, Dumai, Sibolga, Padangsidempuan, Padang City, Pekanbaru, Bengkulu, Gunungsitoli (Pulau Nias), Banda Aceh, Pariaman and Sigli is OK but just acceptable. The sun is not there all the time and you risk you to be soaked by rain frequently. However, if you don't plan a beach and relaxation trip but rather discovery of heritage or hiking, this climate may be good enough for you. In addition, there are certainly fewer tourists dyring this month of december.
But it gets worse: in Palembang, Lac Maninjau, Tebingtinggi, Simpang, Batam, lake Toba, Berastagi, Metro, Jambi City, Bukittinggi, Payakumbuh, Samosir, Pematangsiantar, Parapat, Lhokseumawe, Medan and Takengon and surrounding areas where the climate is very bad. We really do not recommend you to go to these areas this month.
