Baltimore has a humid subtropical climate with four distinct seasons. New arrivals should expect long hot summers and cool winters. Summer, from June to August, is humid and hot with temperatures averaging 27°C (81°F), while thunderstorms do occasionally occur in the late afternoon. Winter, from December to February, is generally mild but snowfall do occur occasionally. Winter temperatures range from 2°C (36°F) to 10°C (10°F) but do drop to -7°C (19°F) depending on the impact of the Arctic air masses.
Spring and autumn in Baltimore are probably the most pleasant seasons, although rainfall is at its highest in the spring. Hurricanes haven’t been much of an issue in recent years, but Baltimore does lie in the path of Pacific storms, and the remnants of hurricanes have been known to cause flooding in downtown Baltimore. This is probably something worth bearing in mind for those considering purchasing property.
