August is Italy’s great migration. Cities empty as millions head to the coast. From August 10–20 (Ferragosto week), Milan, Turin, Bologna, and Rome feel post-apocalyptic: restaurants closed, streets silent, "chiuso per ferie" signs everywhere. The beaches, meanwhile, are sardine tins.
Plan this trip →Everywhere south of Milan: 30–40°C. Rome regularly hits 35°C+. Sicily can touch 42°C. Brutal. Mountains: 12–28°C, the refuge from the heat. Sea temperature: 26–28°C everywhere — bathtub warm.
National holiday. Everything closes. EVERYTHING. Plan accordingly: buy food the day before, have a restaurant reservation, or head to a beach where food stalls operate. The evening of August 15: fireworks in every coastal town.
Cities in early August: Rome/Florence/Milan are actually great the first week — locals leaving means shorter queues. After Aug 10 it’s too dead (restaurants closed). Mountains: Dolomites, Abruzzo, northern lakes are ideal. Islands: stunning but book 4–6 months ahead (Sardinia, Capri, Procida). Puglia/Calabria beaches: crowded Aug 10–20 but amazing early/late August.
Highest of the year for beach/island destinations. Lowest of the year for cities (paradoxically). Rome hotel €80–130 in mid-August vs. €150–250 in June.
