Traveller notes on Bandung in January
Forum posters describe January as squarely within Indonesia's rainy season (roughly October through March), typically bringing a few hours of morning sunshine with temperatures around 78-82F (26-28C) before clouds, thunderstorms and heavy rain move in by late morning or early afternoon. Posters are consistent that rain doesn't fall all day or every day, tending to cluster in the late afternoon or overnight, with an umbrella generally enough to manage it. Posters describe January weather as not cold, just genuinely wet-weather-gear-dependent, and note wet-season visits come with the real upside of far fewer tourists at popular Bandung sites. Posters generally rate January as warm, rain-prone but manageable for a Bandung visit, quieter crowds a genuine trade-off for the wetter conditions.
Other months in Bandung
Forum posters describe Bandung's climate as consistently gentle - never severely hot, never cold - and name May through July as the best overall stretch, squarely inside Indonesia's dry season (which runs roughly May to September, in contrast to the wetter October-to-March period). July itself does hold up as genuinely the driest month of the year by the numbers, even if posters note occasional rain still creeps in some years despite the technically-dry classification - a reminder that 'dry season' here means meaningfully less rain, not none at all. Posters consistently rate Bandung's mild, hill-station-like temperatures (a product of its elevated setting compared to the hotter Java lowlands) as one of its main appeals regardless of exact month.
