Yes, Rome is generally hotter and sunnier than Milan due to its more southerly Mediterranean location. In the summer months (June to August), Rome's average daily highs hover around 30°C to 32°C (86°F–90°F), and it frequently experiences heatwaves where temperatures exceed 35°C. Milan, located in the northern Po Valley, has a more "continental" climate; while its summer highs are similar (28°C–30°C), it is notorious for extreme humidity, which can make the "perceived" temperature feel just as oppressive as Rome. However, Rome's winters are much milder, with average highs of 13°C (55°F) compared to Milan's chilly, foggy 6°C (43°F). Rome also benefits from the ponente—a sea breeze that can cool the city in the evenings—whereas Milan's air can become stagnant and heavy. If you are a fan of traditional sunshine and heat, Rome is the definitive choice, whereas Milan offers a more varied four-season experience with cooler springs and autumns.
