Snowfall is rare, occurring only once every 5 years with 1 inch (2.5 cm) or more falling only about once every decade.

What to Wear in Philadelphia During April?

April is a transition month from winter to Spring so a mix of both winter and spring attire makes the most sense.

You should pack both long and short-sleeve tops, jeans, a few sweaters, sneakers, and some comfortable walking shoes. 

Things to Do in Philadelphia in April

Although it will still probably be pretty cold this month, chances are that there will be a few more sunny days than usual, so you might want to consider taking a pay-what-you-wish Philadelphia walking tour.

April means the opening of the MLB season, and the Philadelphia Phillies are one of the hottest teams in baseball, so you might want to head down to the ballpark this month.

As usual, you can expect at least a few great concerts and musicals to see in Philadelphia this month.
