The summer can be very hot, but families flock to Philly during this time because the children are out of school and there are plenty of free festivals going on. Shoulder season takes place from March to May and September to November. The city is less crowded during the spring and fall, and the weather is pleasantly cool. Low season takes place during the months of December to February. If you are willing to visit during the snowy winter, you can get great prices on plane tickets and hotel rooms.
