Pittsburgh Weather in August

Pittsburgh at the confluence of three rivers has a full humid continental climate shaped dramatically by its river valley topography. The city's steep hills and three rivers (Ohio, Monongahela, Allegheny) create dozens of distinct microclimates between hilltop neighborhoods and valley bottoms. Fog and overcast skies are common and the city historically had severe air pollution (now dramatically improved).

Hot in many cities. Beach and outdoor destinations are at their peak.
