Philadelphia’s weather this week is shaping up to be a typical spring mix—sunshine, clouds, and a few spring showers. With temperatures that are mild enough to enjoy outdoor activities but chilly enough to need a jacket in the evenings, the week ahead in the City of Brotherly Love has a little bit of everything. Whether you’re planning to explore the historic streets, visit a museum, or take a walk along the Schuylkill River Trail, here’s everything you need to know about the weather and how to make the most of it.
Tuesday, March 18: Sunshine and a Mild High
Starting off the week, Philadelphia is experiencing clear skies and mild temperatures. As of mid-morning, it’s already a crisp 34°F (1°C), but the day is expected to warm up to a comfortable 64°F (18°C). For many, today is perfect for a little outdoor adventure, whether you’re strolling through Rittenhouse Square or taking a walk along the famous Liberty Bell.
With plenty of sunshine, the weather should feel pleasant during the day. If you’re out for lunch or walking around the city, you might even feel warm enough to leave your jacket at home—just be sure to have it ready as the evening cools off, dropping to a low of 39°F (4°C). If you’re planning an evening out in one of Philadelphia’s cozy spots, like the Reading Terminal Market or a brewery, you’ll want to layer up for the chillier night air.
Wednesday, March 19: Sunshine with a Side of Clouds
Wednesday will be another beautiful day in Philadelphia, with plenty of sunshine to kick things off. Expect temperatures to hit a high of 68°F (20°C), which feels more like spring than the winter chill we’ve had recently. This is the kind of day that makes you want to grab your favorite outdoor coffee spot or meet friends at Spruce Street Harbor Park.
The mild temperatures are perfect for spending time outside, whether you’re biking along the Schuylkill River Trail or catching a glimpse of the Philadelphia skyline from the Benjamin Franklin Parkway. The low for Wednesday night will be 44°F (7°C), so if you’re heading out in the evening, it’ll still be comfortable, though you might want to have a light jacket or sweater on hand.
Thursday, March 20: Showers and Breezes
As we move toward Thursday, the weather takes a bit of a turn. The day will start off partly sunny, but by the afternoon, there’s a chance for showers and even a thunderstorm. Highs will reach around 67°F (20°C), and although temperatures will still feel comfortable, it’s a good idea to carry an umbrella if you plan to be outside.
It won’t be a washout, but the breezy conditions and potential thunderstorms mean that outdoor plans might need a little flexibility. If you have an afternoon outing or are planning to visit a museum like the Philadelphia Museum of Art, check the weather before heading out. With the storms expected in the afternoon, the weather will cool down again in the evening, with a low of 39°F (4°C).
Friday, March 21: A Cooler End to the Week
After Thursday’s rain, Friday will bring cooler temperatures, with a high of just 51°F (11°C) and a low of 35°F (2°C). The sun will be out, but you can expect breezy conditions to make it feel chillier. It’s the kind of day when you’ll want to bundle up for your walk around the city, especially if you’re planning to head to any outdoor attractions like the Philadelphia Zoo or a tour of historic landmarks.
Saturday, March 22: Cloudy, But Milder
Saturday will see a return to milder conditions with a high of 59°F (15°C) and a low of 40°F (5°C). It’ll be cloudy, but the weather won’t be as chilly as Friday. If you have outdoor plans, it’s a great day to visit the Franklin Institute or catch up on some outdoor shopping. Just be ready for some cloud cover as you explore the city, and pack a light jacket for the cooler evening temperatures.
Sunday, March 23: A Calm End to the Week
By Sunday, the weather will calm down, with temperatures reaching 55°F (13°C) during the day. Expect more sunshine than clouds, and while it won’t be overly warm, it’s the kind of day that makes you want to enjoy a leisurely afternoon walk. If you’re looking for a quiet way to end your weekend, consider spending some time in the city’s many parks or enjoying an outdoor brunch.
Severe Weather and Safety Tips
Although thunderstorms are expected on Thursday afternoon, the weather doesn’t seem too severe, but it’s always wise to stay updated with local weather alerts. If you have outdoor plans on Thursday, be sure to check the forecast before heading out. And, as always, if a storm pops up, it’s safest to seek shelter and wait until it passes.
