Hottest Octobers in Pennsylvania Since 1895
The data shows October 2024 ranked among the warmest on record, with average temperatures and precipitation patterns documented across 129 years of state climate records.
Stacker compiled a ranking of the hottest Octobers using data from the National Centers for Environmental Information, with rankings based on the highest average temperature recorded each month.
Climate change is driving rising temperatures and more record heat; the Earth's temperature has climbed each decade by roughly 2 degrees Fahrenheit total since 1880.
For each of the hottest months listed, reports include average state temperature, state-wide highs and lows, and total precipitation; specific records show totals of 3.89 inches.
The continental United States experienced its hottest month on record since 1895, according to data from the National Oceanic and Atmospheric Administration in July 2026.
