About Allentown

Allentown PA

Allentown PA is one of the fastest growing cities in the United States, and it is also one of our favorite places to serve our customers. Located on the Lehigh River, Allentown was one of only six communities in the country to be cited as a national success story in April of 2016. The Urban Land Institute presented this honor on Allentown for the redevelopment and transformation of its downtown location.

One of Allentown’s claim to fame is the fact that they hid the Liberty Bell from the British during the American Revolutionary War. The Pennsylvania Supreme Executive Council assigned two local resident to hide the Liberty Bell in the Old Zion Reformed Church that is now center city Allentown.

In 1861 Allentown answered President Lincoln’s call for volunteer troops to defend the nation’s capital. They sent a unit called the Allen Guards to protect and guard the capital for three months. The Allen Guards helped to prevent the city from being captured by Confederate soldiers and they came to be known as the Pennsylvania First Defenders.

Lehigh Valley and Allentown have a unique history due to the barter exchange that was used when they were originally purchased by William Penn’s sons John, Thomas and Richard. The Penn brother’s made the agreement to barter the land from 23 Native American Chiefs with an offer of clothing, weapons and other miscellaneous items.

Local Weather


Allentown, Pennsylvania, 2010
Summers in Eastern Pennsylvania are hot and very humid, with temperatures in the mid-80s and low-90s. The average high temperature peaks at 84 °F (29 °C), but highs can often surpass that, with the all-time record high standing at 105 °F (41 °C). Humidity is often around 80 percent, which is a drastic change for someone living in the Southwest United States. Rain is common, and is often accompanied by strong or severe thunderstorms. These will cause quite a large amount of rain, but they do not last long at all. Air conditioning is popular among most households in the summer months, because high temperatures and high humidity can make the air feel much warmer than the actual temperature.


Autumn is fairly mild, with daytime temperatures in the 70s and 60s. Autumn brings more wind, and sometimes heavier rainfall. Trees begin to lose their leaves before the cold winter season. Indian summer may occur.


Winters are cool to cold, with January’s high temperature at 35 °F (2 °C). The highest temperature recorded was 76 °F (24 °C) in February, 87 °F (31 °C) in March, and 72 °F (22 °C) in both December and January. Snowfall is common, with amounts varying greatly between seasons. Snow, ice, sleet, and freezing rain can cause road problems and school closures. In February 2007, Interstate Highway 78 was closed just west of the city. Drivers were stranded on the stretch of highway for as much as 24 hours, with overturned tractor trailers blocking the way. Winter sports are popular, such as snowboarding and skiing, and they can be enjoyed in the Pocono Mountains, just north of the Lehigh Valley.


Spring is a season of growth, with new grass growing and flowers blooming. Animals come out of hibernation, and sun fills the city and its surroundings. Temperatures are on the rise, but March and April bring much rain, with light rain that can last for hours on end. That gives way to warm May and June months, and shore weather is in the forecast for many residents.
