As the summer heats up, so does the city. Families on vacation head here for history, with crowds surfacing near historic attractions, like the Liberty Bell. The city also sees an influx of visitors around the July 4th holiday, when free concerts by blockbuster musicians are held on the Parkway, followed by fireworks. Expect to pay at least 20% more for a hotel during the summer months, and book at least a month in advance to secure a hotel room during the July 4th festivities.
It seems hotel prices follow the thermometer here, with the best deals being had when the mercury drops. While the weather can dip well into the freezing range, and snow is a standard part of Philadelphia winters, temperatures typically range from 70 degrees in September to 30 degrees in February. If you're seeking a white winter, December through February can be one of the best times to visit Philadelphia. All of the city’s main attractions remain open throughout the winter, which, when coupled with thinned crowds, make a strong argument for visiting Philadelphia during the winter months—just don’t forget your mittens.
Spring brings moderate weather and moderate hotel prices to the City of Brotherly Love. Temperatures hover in the mid-50s and -60s and the sidewalks are noticeably less packed with crowds than in the summer months. The city is in bloom, from flowers in Rittenhouse Square to the cherry blossoms in Fairmount Park, providing a beautiful backdrop for vacation photos. If you’re coming to get a history lesson, know that groups of school kids mob virtually every historical tourist attraction during these months, so come mentally prepared or adjust your plans.
