Berlin is famous for its summers—not that they’re especially warm, but there is just so much to do. The summer season can be wet, so it’s best to pack an umbrella—though rain doesn’t stop Berliners from enjoying their city. May is often considered the best time to visit, with good weather and plenty of festivals and events. Winters in Berlin are cold (below freezing in January and February), but the cultural events don’t disappear. Locals stay busy with seasonal festivities and quirky adventures like skiing on the grounds of the former Tempelhof Airport, which is now a giant city park.
