Any time is right to enjoy the area's attractions, and a variety of popular annual events takes place throughout the year. To avoid the largest crowds and be assured that all seasonal attractions are open, visit in May–June or September–October. If you don't mind waiting in longer lines to see popular attractions, visit around July 4, when the city comes alive with fireworks, parades, and festivals. The top draw is the Wawa Welcome America! festival, which often includes a performance by a blockbuster musician or two. There are special activities in the Historic Area all summer long. Concert and theater seasons run from October through the beginning of June—but the World Champion Phillies play from summer through the fall. You may find some better lodging deals—and a beautiful snowfall—in winter, if you don't mind bundling up. In spring the city's cherry blossoms bloom, rivaling those of the Tidal Basin in Washington, D.C.
Like other northeastern American cities, Philadelphia can be hot and humid in summer and cold in winter (winter snowfall averages 21 inches).
