When to go
Tambora can be climbed all-year, however the best time for trekking is during the dry season, i.e. June to October. November brings fresh rain to the rainforest and the trail starts to be slippery, with regular heavy afternoon showers. From what we heard December can be already very wet and January to March are the toughest months to visit. In April and May trail conditions gradually improve.
