Beaver County averages 50.5°F annually, sitting about three degrees below the national median. Its 40.5 inches of precipitation is relatively moderate compared to the more humid eastern parts of the state. This creates a climate that is representative of the Upper Ohio Valley, with distinct but not overly extreme seasons.
A drier corner of the Commonwealth
Beaver County is slightly warmer than the Pennsylvania average of 49.9°F, but it is much drier. It receives nearly 5 inches less annual precipitation than the state average of 45.3 inches. This relative lack of moisture makes it one of the less humid counties in the Western Pennsylvania region.
Lower extreme heat than its neighbors
Beaver County experiences only 9 days of extreme heat above 90°F, which is significantly fewer than the 15-17 days seen in neighboring Allegheny and Armstrong counties. While its average temperature is 50.5°F, it avoids the urban heat intensities found closer to Pittsburgh. Precipitation remains consistent with other counties along the Ohio River corridor.
Cool summers and frozen winters

Winters average 30.0°F from December through February, with January being the coldest month at 27.8°F. Snowfall data is currently unavailable, but the winter temps suggest consistent frost throughout the season.
