What to expect
Daytime
Hot days in Indonesia. Ruins, markets and hills are a morning job. Midday sightseeing is how people remember January for the wrong reason.
Nights stay warm. Air-con, if you can get it, is part of the brief. A jumper for January in Indonesia is almost always a waste of bag space.
Rain
January is a wetter month in Indonesia. Showers are part of the deal, not a spoiled surprise.
Waterproof shoes matter more than a rain plan for a beach, especially if a beach is not why you came. Build indoor hours into the afternoon.
Evening
Evenings stay warm.
