- Humidity Levels
- Atmospheric Pressure Changes
These factors contribute to the overall weather patterns experienced during October in Philadelphia.
-
Seasonal Transition:
The seasonal transition from summer to fall significantly influences October’s weather in Philadelphia. As summer ends, the average temperatures tend to decrease. According to the National Weather Service, October temperatures in Philadelphia typically range from the upper 40s to low 60s Fahrenheit. The change in weather patterns is marked by cooler air masses moving in from Canada, leading to a drop in temperatures. -
Geographical Location:
Philadelphia’s geographical location on the East Coast contributes to its October weather. The city lies between the Atlantic Ocean and the Appalachian Mountains. This positioning allows for maritime influences, which can lead to fluctuating temperatures and precipitation levels. The proximity to the ocean may also result in slightly milder temperatures compared to inland areas. -
Humidity Levels:
Humidity levels play a key role in the weather experienced in October. During this month, humidity often decreases as temperatures drop. This lower humidity can lead to clearer skies and drier conditions. Data from the Weather Prediction Center indicates that average relative humidity levels in October range from 60% to 80%, affecting the perceived temperature and comfort levels. -
Atmospheric Pressure Changes:
Atmospheric pressure changes can significantly affect weather patterns. In October, Philadelphia experiences variations due to shifting weather systems.

The National Oceanic and Atmospheric Administration (NOAA) notes that October typically has increased storm activity due to these pressure changes, impacting local weather conditions.
How Does Precipitation Affect the Average Temperature in October in Philadelphia?
Precipitation affects the average temperature in October in Philadelphia by influencing humidity and cloud cover. When it rains, the moisture in the air can make temperatures feel cooler. This cooling effect occurs because rain evaporates, absorbing heat from the surrounding environment. Additionally, cloudy skies resulting from precipitation can trap heat at night, leading to warmer overnight temperatures. However, on days with significant rain, the overall average temperature may drop due to reduced sunlight and cooler conditions during daytime. Therefore, increased precipitation in October can contribute to fluctuations in average temperature, generally resulting in cooler days and milder nights.
What Is the Historical Temperature Trend for October in Philadelphia?
