In terms of beautiful weather and moderate crowds, March through May and September through November are the best times to visit Maryland. Spring enveils with warm air and brings numerous events like the Maryland Film Festival or Maryland Craft Beer Festival. Fall is mild but also a bit rainy and windy. The rooms during this time are moderately priced, so don't hesitate to visit Baltimore for its famous Maryland Fleet Week & Air Show. June through August is the busiest period in Maryland. Summer here means comfortable weather and moderate precipitation but also higher rates. But being here, make sure you attended the marvelous Maryland Lavender Festival. The weather gets very cold in December. Snow and rain are possible all winter long, but the prices are at their lowest. There are fewer tourists as well, so you can fully enjoy the numerous Christmas lights around Maryland.
