Traveller notes on Makassar in August

Forum posters describe August as sitting in the region's drier season, with generally good conditions for travel compared to the wetter months, even though some rain remains part of the picture rather than a fully dry stretch. Temperatures are described by one poster as 'a bit hot, just like Brisbane in December' - warm and humid but not extreme. Posters recommend Makassar as a worthwhile stop for diving, fishing and jetboat activities on the water, generally framing it as an underrated base compared to more heavily-touristed parts of Indonesia, with August's drier conditions supporting a full slate of outdoor activities.

Other months in Makassar

Forum posters discussing Indonesia's wider wet season note February typically runs a bit drier than January, though rain remains a real presence and some posters describe daily rain potentially continuing well into May depending on the year. It's worth noting Makassar's own 12-month climate record backs the drier-than-January comparison (about 26 rainy days in February versus January's 30) but doesn't support treating February as close to the season's end - the city's genuinely drier stretch doesn't arrive until around July-September. Posters describing Makassar itself note it runs hot in a similar way to Brisbane in December, with southern Sulawesi generally considered a reasonable place to be this time of year despite the rain. Posters generally rate February as still solidly wet season for Makassar, marginally better than January but far from the year's driest stretch.
