Maryland is a Mid-Atlantic state of striking contrasts: historic Chesapeake Bay crab country, Appalachian mountain ridges, Civil War battlefields, and the vibrant harbor city of Baltimore. Flanking Washington DC on three sides, the state blends federal grandeur with blue-collar charm, colonial waterfront towns, and some of the East Coast's finest seafood.
Maryland has a humid subtropical climate (Chesapeake coastal regions) transitioning to humid continental in western mountain counties. Summers are hot and humid with average highs of 87°F (31°C) in July and high humidity making it feel 95-100°F. Winters are cold but moderate — Baltimore rarely drops below 20°F (-7°C), though western Maryland gets significant snowfall (40+ inches per year in Garrett County). Spring and fall are the most pleasant seasons with mild temperatures, lower humidity, and minimal rain.
