The weather is completely unpredictable in Philadelphia. One year, winter will last until May, and the next, summer doesn't seem to go away. Scarves and hats are also essential for the wind chill. It'll rain every day in the spring and half of the winter, so students should bring two umbrellas, as one will surely get destroyed in the wind. If students are going to buy an umbrella from either the Drexel or Penn bookstores, make sure to do so on a nice day. The minute it begins to rain, all of the umbrellas disappear. It is also important for city dwellers to remember not to stand or walk too close to the edge of the sidewalk in the rain, especially when waiting for a traffic light to change. If they do, they will get sprayed by a passing car, and they will not dry off for a very long time.
Philly summers are notoriously hot due to the city location. As long as students know this and dress accordingly, no issues should arise—aside from some sweat.
