Philadelphia, Pennsylvania Weather in May

May weather

May is one of Philadelphia's best months for walking around. Afternoons feel mild, evenings turn cool, and spring brings leafy streets and parks. The average high is 22°C, with 11 rainy days, so showers can interrupt a day out.

You can explore Old City, stroll the Schuylkill River Trail or picnic in Rittenhouse Square. Rain can make long outdoor plans a bit hit-or-miss, so keep the Barnes Foundation or Reading Terminal Market in mind for a wet afternoon.

Events and crowds

The South 9th Street Italian Market Festival usually takes place in May. Expect food stalls, music and crowds around the Italian Market. Memorial Day weekend also draws visitors, especially to the historic sights.

May is popular, and hotel prices can rise on event weekends. It's generally a busier, pricier time than winter, but summer brings more heat and crowds. If you hate crowds, visit Independence Hall on a weekday and leave the festival streets for later in the day.

Local tips for Philadelphia

May's long daylight gives you time to combine sights without rushing. Walk from the Liberty Bell through Old City, then head to the waterfront. When rain rolls in, Reading Terminal Market is a handy place to sample a roast pork sandwich or warm up over lunch.

For Independence Hall, reserve a timed ticket through the National Park Service; demand can be high in spring. Travelling with kids? The Franklin Institute is a good rainy-day stop, close to Logan Square and the Benjamin Franklin Parkway.
