No matter what time of year you pass through Berlin, there's a strong possibility that you'll come across a world-class cultural event. In January and August, Lange Nacht der Museen (Long Night of Museums) means the likes of the Gemäldegalerie and the Neues are open until 2 a.m. In February, hit the Berlin International Film Festival, one of the most prestigious and celebrity-heavy events in all of cinema. Come May, the Karnevel der Kulturen (Carnival of Cultures) celebrates the 500,000 non-Germans—from 180 countries—who call Berlin home.
The climate is generally continental: warm, sometimes humid summers (with highs of around 86); cold and damp winters (lows of 28); and moderate rainfall throughout the year. Expect light snow to sift down between December and March, though it rarely sticks around for more than a few days—and if there isn't snow, there's frost. Bring a hat, scarf, and gloves in winter. August is the most unpredictable: Days may kick off without a cloud in the sky, and by afternoon, you'll be ruing the umbrella you left in your hotel room. And here's a tidbit: The center of Berlin, with the density of its buildings, actually has its own microclimate—sometimes it's four degrees warmer in the city than in the outskirts.
