Sofia's climate is one of its best attributes. Situated on an open plain only 1,804 feet (550m) above sea level and ringed in by the Balkan and Vitosha Mountains, summer days in the city are warm and sunny, with temperatures occasionally inching above 86ºF (30ºC). Winters are cold and snowy, when temperatures usually drop to around 38°F (3°C).Summer is the peak tourist season but winter also attracts many visitors to the ski slopes. Spring and autumn are pleasantly mild seasons and both are known for their beautiful colours. Sofia is, indeed, a year-round tourist destination.
