Bologna in May

April through June offers ideal weather for walking Bologna's porticoed streets. Temperatures hover around 20°C, and the spring light makes the terracotta buildings glow. Restaurant terraces reopen, and the university crowd brings energy to the streets. September and October deliver another sweet spot. The summer crowds thin out, but weather stays pleasant for exploring. This is truffle season in nearby hills, meaning restaurant menus get even better. July and August can be sweltering, with temperatures reaching 35°C and high humidity. Many locals escape to the coast, leaving some restaurants closed. But the porticoes provide shade, and gelato shops work overtime. Winter brings fog and chill, but also a cozy atmosphere perfect for long meals and wine bars. December markets add charm, though some outdoor attractions close or reduce hours.
