Maryland Climate and Weather

Maryland has four distinct seasons and its landscape varies from sea-level plain to low mountains, the weather is generally not that extreme. The state is prettiest in the spring, when the dogwoods and fruit trees are blooming, and in October, when the landscape glows with myriad shades of gold. At those times, weather is changeable, with warm temperatures (50-77 F/10-25 C). Summers can be quite warm, with average temperatures in the mid 80s F/29 C. Fairly high humidity (near 70 %) July-August can make for some uncomfortable touring, but sea breezes help keep coastal areas more comfortable, and cooler night temperatures give a break from the heat. The mountains in the western part of Maryland are generally cooler and wetter than elsewhere. Maryland does get snow most winters, with accumulations of 1-70 in/2.5-178 cm (the mountains get the most). A few attractions close during the winter months, but nearly all are open during the spring, summer and fall seasons.
