If you are planning an urban getaway to Philadelphia, spring (April to June) is spectacular. The humidity hasn't quite spiked, and events like cherry blossom blooming or a walk through the stunning Longwood Gardens are very comfortable. Summer is the peak season for family road trips, particularly to Hershey and the State numerous state water parks. However, be prepared for intense heat and humidity if you're spending July and August navigating the historic, brick-paved streets of Center City. Winter caters to snow enthusiasts with skiing and snowboarding resorts scattered across the Poconos and the Allegheny Mountains, making the state a true year-round destination.
