Traveller notes on Bari in September
Other months in Bari
Forum posters describe November in Bari and wider Puglia as genuinely variable, sometimes mild during the day - one visitor described the first few days of a trip as warm enough to sit outside in short sleeves - but consistently dropping cold at night, cool enough that outdoor evening dining isn't really an option even when daytime feels pleasant. Posters cite typical daytime temperatures around 8-12C with sunny spells especially around midday. Posters are direct that torrential downpours are a real and common feature of southern Italy this time of year, though one visitor's early-November trip saw only light, infrequent rain. Posters describe the overall pattern as a genuine gamble across different years - one November bringing beautiful spring-like weather, another turning chilly and rainy. Posters generally recommend flexible plans and layers for a November visit to Bari.
Forum posters call May close to perfect for Bari and Puglia generally - daytime highs well into the 20sC (one May trip report logged a typical high around 78F) without the summer crowds. The one caveat repeatedly raised: the sea hasn't had a full summer to warm up yet, so swimming is a cooler prospect than the pleasant air temperature might suggest, and weather itself isn't fully guaranteed to cooperate this early in the season. Bari's old town - the alleyways, and watching the local nonne hand-roll orecchiette right outside their homes - is the most-recommended single experience, with posters also pointing toward easy day trips to Alberobello, Matera, Ostuni and Lecce for anyone with extra time.
