The climate of Maryland (United States of America)
Maryland is located on the east coast of the United States, partially on the Atlantic Ocean and for a large part on Chesapeake Bay. Because many suburbs of Washington DC are located in Maryland the state is home to a lot of civil servants who work in the capital of the US. Maryland has the highest per capita income. The state is also home to many scientists and many leading schools can be found here. In the field of logistics Maryland is also an important state; Baltimore is among the 20 most important ports in the United States.

Maryland is quite oddly shaped; because of this two climate zones can be distinguished. The eastern part of Maryland has a warm maritime climate (type Cfa according to the Köppen climate classification) with warm and wet summers and mild winters. The western part of Maryland has a moderate maritime climate (type Cfb) with cooler in winters and more snowfall. The amount of snow that may fall as well as temperatures are determined by the altitude at which a city is located. In the mountains in the west 250 centimeters of annual snowfall can be recorded on average. Along the coast only 20-25 centimeters of annual snow falls.

Summers are warm in Maryland. In July and August maximum temperatures may rise up to 28-33 degrees Celsius (82-91 degrees Fahrenheit). There is a risk of tropical storms and hurricanes in this state. However, most hurricanes make landfall in Virginia and North Carolina first. Because of this wind speeds as well as precipitation figures have decreased before reaching Maryland. However, in theory a full force hurricane can hit Maryland.

More climate information
Climate tables are useful but they don’t give an overall picture of the climate and possible weather conditions during a period of time. How high the chances are of hot or cold weather or hurricanes can often not be found in these tables. This is why we offer extra climate information per month. The figures below apply to Annapolis. For climate figures on specific regions and places please, visit the relevant individual climate pages.
