Central Pennsylvania has four very distinct seasons, and students should bring attire to match any kind of weather. In the winter, it gets pretty cold and snows a decent amount, so be prepared to need snow boots for walking to class. The spring and fall are mildly warm, depending on the type of season the area is having, but it varies from both extremes. Also, never forget your umbrella because you never know when a cloud is going to burst open here! Carlisle is situated in a broad valley of the Appalachian Mountain chain called the Cumberland Valley, and clouds tend to get trapped in the valley and stay for longer periods of time here than they do in the rest of the Central Pennsylvania. This makes Carlisle seem like a very dreary place sometimes because it is often overcast and/or rainy.
Students complain about Carlisle weather constantly, and not too many kids are fond of the local weather patterns, with the exception of the ski club in the winter. The worst months for rain are usually October, March, and April, so make sure you have your rain boots! Whenever it is nice out, students appreciate the weather and take full advantage of it because these days can sometimes be very few and far between.
