The city is teeming with life in summer, which can start in May and may continue into October, with its open-air parties and plentiful street festivals. Your second-best bet is the Christmas and New Year season, when you can delight in the seasonal markets, hot wine sold by street vendors and fireworks.
Germans are known for two virtues: efficiency and punctuality, and the two are linked. This applies to their effective BVG transport system, with trains, trams and buses which operate 24 hours a day (remember, Berlin is an all-night party city); a single-ride ticket starts at $1.75.
July is the hottest month, with an average high of 64°F (18°C). January is the coldest month, with an average high of 30°F (-1°C).
You may experience some culture shock when you arrive—the city is incredibly permissive, and anything goes. And don’t be put of by the notorious “Berliner Schnauze.” Berliners, especially long-standing natives, can be testy and a bit biting. Don’t let it slow your pace.
