Philadelphia, Pennsylvania Weather in April

April feels changeable

April brings mild afternoons and cool mornings. You'll want a jacket for a walk along the Schuylkill River Trail, especially near sunset. Rain falls on about ten days, so showers can interrupt a day outside. The upside is nearly thirteen hours of daylight for fitting in sights.

The weather works well for exploring Old City, Independence Hall and Reading Terminal Market. Save a long picnic or a full day at the Philadelphia Zoo for a drier forecast. April is spring, but it doesn't feel like May's warmer weather yet.

Blossoms and spring events

The Subaru Cherry Blossom Festival often takes place in April at Shofuso Japanese Cultural Center in West Fairmount Park. Its bloom timing can shift with the weather, so the flowers aren't guaranteed on a particular day. The Philadelphia Science Festival also usually brings hands-on events around the city.

If you hate crowds, visit Shofuso on a weekday rather than during a festival weekend. Cherry blossoms draw visitors, but April is generally calmer than summer's peak travel period. You'll often find fewer people and better-value stays than in the busiest months, though prices vary by date.

Make rainy hours count

Travelling with kids? A wet afternoon is a good excuse to explore Reading Terminal Market, where you can try a soft pretzel or a roast pork sandwich. It's a useful indoor stop, not just a place to eat.

For a local outing, take the Market-Frankford Line to 15th Street, then walk up the Benjamin Franklin Parkway toward the Philadelphia Museum of Art. If rain rolls in, duck into the museum instead of pushing on to the steps. The April weather can change quickly, and that route gives you an easy indoor option.
