Bari has a hot-summer Mediterranean climate (Koppen Csa) with mild, wet winters and hot, dry summers. As a coastal city on the Adriatic Sea, temperatures are moderated by the water, avoiding the extreme heat of inland Apulia. The city averages 2,600 sunshine hours per year, among the highest in Italy, and rainfall is concentrated in autumn and winter months. Sea breezes from the Adriatic keep summer evenings comfortable even when daytime highs reach 32°C (90°F). For more context, see our complete Bari travel guide.
