Although it is not perfect the weather in Sumatra in january should be pretty good in Banda Aceh and Sigli. I allows to savor tours in these places. And even why not take a little time to take a nap at the pool under the sun!
If you do not go to spend your time in a lounger by the pool, but, for example to go sightseeing, the cities of Langsa, Tanjungpinang, Tebingtinggi, Gunung Leuser National Park, Simpang, Kisaran, Batam, Bukit Lawang, Dumai, Jambi City, Samosir, Sibolga, Padangsidempuan, Pematangsiantar, Parapat, Padang City, Lhokseumawe, Pekanbaru, Medan, Bengkulu, Gunungsitoli (Pulau Nias) and Takengon have a quite correct weather for it in january. Eventually, it is not advisable to travel in the cities of Palembang, Lac Maninjau, Bandar Lampung, lake Toba, Berastagi, Metro, Bukittinggi, Payakumbuh and Pariaman in january because the climate is bad.
