Spring (April-May): Ideal weather with temperatures 18-25°C (64-77°F), wildflowers blooming, fewer crowds, and perfect conditions for sightseeing and outdoor activities. Easter celebrations add cultural richness.
Fall (September-October): Warm sea temperatures (23-26°C), summer crowds dissipating, pleasant weather for walking, and cultural events like Notte Bianca (all-night arts festival in October).
Summer (June-August): Hot and crowded with temperatures 28-35°C (82-95°F). Peak tourist season means higher prices and fully booked attractions. Best for beach lovers but challenging for extensive city walking. Book accommodations and popular sites well in advance.
Winter (November-March): Mild winters (12-18°C) with occasional rain. Fewer tourists, lower prices, and authentic local atmosphere. Some attractions have reduced hours. Perfect for budget travelers and those seeking cultural immersion without crowds.
Best overall: May or September-October offer the sweet spot of great weather, manageable crowds, and reasonable prices.
