Try shopping for an apartment in November in Newark. You won't have quite as much to choose from as in the summertime, however, you also won't have nearly as many people looking for a new apartment. It's a good time to strike a balance between availability and competition.
Newark is home to some great rental units, and some that are not so great. Always get a look at an apartment and meet with the landlord in person before you sign any agreements. Otherwise, you could find yourself legally locked in to a less than ideal situation very quickly.
Newark has excellent public transportation. While a person certainly could opt to drive, the traffic makes it a very frustrating exercise. There is a bus system that can easily get you anywhere in the city, including the suburbs. Newark City Light Rail has two lines that branch off from Penn Station and can quickly get you to major areas.
Newark Residents are passionate about the Devils, so taking in an NHL game is a great way to meet some more locals. The Prudential Center is also a major concert venue that has hosted some of the biggest acts in the world. The largest museum in the entire state is the Newark Museum. The Mills at Jersey Gardens is a huge outlet mall that is a great place to go if you like shopping for a deal.
