Spring
While there’s always the threat of rain, spring in Milan is generally quite mild and pleasant. And when the sun comes out, the normally-moody city takes on a warm glow, with the sunlight highlighting all the unique design details and flourishes, from elaborate wrought-iron balconies to zoomorphic sculptures. Every April the city hosts Salone del Mobile, often referred to as Milan Design Week, a huge design event focusing on the future of furniture. If you don’t mind crowds, it’s a must-see spectacle.
