A continental climate ensures that Bucharest experiences hot, dry summers and cold winters when temperatures often drop well below freezing. The city lies on the Romanian Plain, and this brings chilly winter winds. Summer is the best time to visit, as temperatures are usually pleasantly warm with occasional heat waves, and humidity is low, but there can be occasional rainstorms. In summer (June to August), temperatures average between 57°F (14°C) and 95°F (35°C), and in winter (December to February), temperatures average between 22°F (-6°C) and 39°F (4°C). The rainiest seasons in Bucharest are spring and autumn.
