Philadelphia Weather - The weather in Philadelphia varies greatly by season. Like most of the Mid-Atlantic States in America it has for very clearly defined seasons. The season when most people choose to do their traveling is summer. In Philadelphia in the summer temperatures will average, during the day, somewhere between 70 and 90 degrees.

Fall is a lovely time to visit Philadelphia, the leaves are turning colors and you can still go out without a jacket. You’ll want to pack warm pants and some sweaters, but leave your ski jackets at home. On a warm fall day you may encounter 70 degree weather and on a cold one somewhere near 50 degrees. One last word to the wise, if you come in fall plan on encountering rain.

Winter is amazing in Philadelphia. The one thing I can tell you is plan on snow, not a blizzard mind you, but during the winter season this region is prone to getting snow. The tricky part is that the regions snow fall varies greatly from year to year. Some years you can go a whole winter without seeing more than 10 inches and some years you’ll get 10 inches in one snowfall.
