When is the best time to fly Philadelphia?

Peak Season:

Summer months of June to August are the peak season, which experiences temperatures on average between 21 and 29 degrees Celsius. The pleasant weather makes for a great time to explore the city, but bear in mind this season attracts the most crowds. As this is the most popular time, accommodation and flights to Philadelphia will be more expensive.

Off Peak Season

The off-peak season starts in autumn (September – November) and although temperatures are mild, winter soon arrives, which is cold in Philadelphia, with temperatures generally below freezing. If you can brave the chilly weather, however, you’re likely to find fewer crowds, discounted hotels and cheap flights to Philadelphia during this time.

Shoulder Season:

Spring can still be busy although the crowds will be smaller than the peak months. This can be a great time to book a holiday, as the weather will usually be around 1 to 10 degrees in March and 10 to 21 degrees in May, and prices will generally be slightly cheaper than during the summer months.

Be aware, however, that Philadelphia is home to hordes of students and 80 regional colleges and universities so plan your trip to avoid the autumn arrival and spring exodus of all those students.

City overview

There is so much to do and see in Philadelphia that it’s hard to know where to start. For most visitors to Philadelphia, it’s best to start at the beginning. After all, this is where the “Declaration of Independence” and the Constitution were written and signed, thus signalling the beginning of American freedom and civil liberties.

Today, travellers to Philadelphia gear up for a whirlwind history lesson. Sure, there’s the Liberty Bell, the signing of the Constitution and Independence Place, but if you look closely you’ll find that history runs deep within the city limits. Pay close attention to the hotels – look closely and you’ll see a combination of old Philadelphia combined with the new world. Philadelphia is packed full of cobblestone streets, grand halls and historic homes.

Movie lovers can run up the stairs of the Capitol building – just like Sylvester Stallone in Rocky – and then stand in line for cheese steak at one of the city’s famous stands. Sports lovers book flights to Philadelphia to cheer on the Eagles, the Phillies, the Flyers and the 76ers.

If you have a day spare then take a flights across to Newark and see the Thomas Edison National Historical Park, flight times are around 30min while a drive will get you there in 2hrs.
