When Does Rain Fall Most Often in Philly?
This June brought more rainfall to Philly than any other June in recorded history. And as Axis Philly observed, much of the torrential downpouring seemed to be occurring in the late afternoon and early evening. Typical? Atypical? Analyzing information collected since 1990 by 24 rain gauges throughout the city, Axis found that the most common period of rainfall was in July, from 7-8 p.m. In total, during that time frame, the city has accumulated 7.2 inches of rain over the past 23 years.
Why? As a meteorologist told Axis, thunderstorms are more common during summer months, due to humid air rising throughout the day. And because God hates Center City Sips. [Axis Philly]
