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.
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.
Icy cold winters and extremely humid summers make spring and autumn the best time to take flights to Philadelphia. If you can handle the crowds, Philadelphia goes wild every 4th of July (Independence Day) with fireworks and city-wide celebrations.
A quick and easy way to get around the city centre is the Phlash, Philadelphia’s gas-engine trolley. It’s a convenient way to get to Independence Visitor Centre, Penn’s Landing and the Philadelphia Museum of Art. The trolley runs every day and can be boarded every 12 minutes at very affordable rates. It also provides direct connections to rail lines.
The main airport for travellers taking flights to Philadelphia is Philadelphia International Airport (PHL). There is a shuttle available from the airport and transfer time is about 30 minutes. Car rental companies operate at the airport as well as limousine service.
Philadelphia International Airport is the largest airport in Pennsylvania and an international hub for US Airways. It’s also the main gateway to Philadelphia and Pennsylvania generally.
Philadelphia itself, affectionately known as Philly, is often referred to as “the Birthplace of America”. With a rich and varied history, it’s the fifth-largest city in the US, and has a metropolitan area spanning 12 counties. As a result the atmosphere, architecture and demographic varies quite widely depending on which area you travel to, from up-market art and design centres and historic quarters to working-class areas and quiet, leafy suburbs.
The airport is one of the busiest in the world. It has seven terminals, two of which are international terminals, and more than 160 shops and eateries. The immigration counters are notorious for being understaffed and poorly organised and long queues are common, so if you’re catching a connecting flight, make sure you arrive well in advance.
Philadelphia (PHL), located 7.0 mi from the city centre, is the airport you fly into when you book flights to Philadelphia.
