With diverse topography and mixed climate zones, Pennsylvania experiences a wide range of weather patterns throughout the year. Rainfall plays a distinct role in Pennsylvania’s ecology, whether for agriculture, lifestyle, or the local environment.
The majority of Pennsylvania has moderate rainfall throughout the year. However, certain cities (and towns) in the state consistently rank the highest in terms of annual average rainfall.
We have shortlisted the eight rainiest cities in Pennsylvania and will explore the details about their average rainfall and how it impacts the local ecosystem there.
1. Erie
Average Annual Rainfall: ~45 inches
Erie is the most weather-active of the lot among the different Pennsylvania cities. Since the city is located adjacent to Lake Erie, it experiences extreme weather conditions in terms of rainfall and snow. Instead of experiencing rainfall for certain months, Erie remains wet throughout the year due to the consistent precipitation patterns. While there, start exploring with Presque Isle State Park, a stunning peninsula with beaches, walking trails, and wetlands. You can also head to the Erie Maritime Museum to learn about the city’s naval history. For families, especially ones travelling with kids, Waldameer Park & Water World is the perfect day trip destination, amidst the rain.
2. Johnstown
Average Annual Rainfall: 44 inches
Johnstown is already renowned for its historical floods and steep terrain, so when highlighting the rainiest cities in Pennsylvania, this deserves a spot in the top 3. Heavy rainfall and flash floods are frequent in this city due to the surrounding ridges and steep hills. However, the consistent precipitation contributes to the lush green scenery in the area. Head to the Johnstown Flood Museum to learn about the chronicles and devastation of the 1889 flood. Also, you can visit and explore the Staple Bend Tunnel, which is part of the Allegheny Portage Railroad, making it a great hiking trail.
3. Pittsburgh
Average Annual Rainfall: 38 inches
The location of Pittsburgh is quite fascinating and explains why it is one of the rainiest cities in Pennsylvania. It is situated at the confluence of three rivers, experiencing moderate to heavy rainfall throughout the year. Since the city is close to the Allegheny Plateau and the river valleys, it contributes to frequent overcast and heavy rainy months. Despite the wet weather, the town boasts scenic riverside views and many spots to explore. Among them, you can start with the Point State Park, which is located in the area where the three rivers meet. For plant lovers, consider exploring the Phipps Conservatory and Botanical Gardens, which is even more beautiful during the rainy season.
4. Allentown
Average Annual Rainfall: 46 inches
Featuring a humid continental weather with year-round precipitation, Allentown is another rainy city you can add to your travel plans in Pennsylvania.

5. Harrisburg
Average Annual Rainfall: 42 inches
Harrisburg is the state capital and boasts a humid subtropical weather with frequent summer storms. This explains why the summer and warm months are often more comfortable in the city.

Even on the rainy days, the river offers a relaxing backdrop for the visitors. If you want to witness the intricacies of the American Renaissance architecture, head to the Pennsylvania State Capitol Complex first. Also, for stunning river views and walking trails, the Riverfront Park is a great destination. You can also visit the National Civil War Museum to learn about the history of the Civil War.
6. Scranton
Average Annual Rainfall: 41 inches
Not just heavy rainfall, Scranton is also known for experiencing heavy snowfall during the winter months. Located in northeastern Pennsylvania, primarily in Wyoming Valley, Scranton’s heavy rain contributes to the lush greenery and the dense forests in the area. While the city’s industrial revolution is quite fascinating, it is equally renowned for its cultural scene and nature. The Steamtown National Historic Site is one of the most iconic destinations, enabling you to learn more about the steam locomotive era. You can also go on an underground adventure with the Lackawanna Coal Mine Tour, which takes you into a former coal mine. To bask in the beauty of nature, Nay Aug Park is also a great destination for witnessing waterfalls and walking through gorge trails.
7. Wilkes-Barre
Average Annual Rainfall: 40 inches
Wilkes-Barre often experiences diverse weather patterns and is located quite close to Scranton. Much like Scranton and many other cities in the Wyoming Valley, even Wilkes-Barre experiences heavy rainfall and snowy winters. The town surrounding the Pocono Mountains also benefits from extensive rain. One of the most picturesque spots in the area is River Common, a scenic park along the Susquehanna River. You can also visit the Seven Tubs Nature Area to witness naturally formed “tubs” and the streams around. For the entertainment freak in you, Mohegan Sun Arena is a great spot to enjoy concerts.
8. State College
Average Annual Rainfall: 39 inches
