Stacker Ranks the Hottest Octobers on Record Across Ten U.S. States

The state rankings are ordered by each October’s highest average state temperature, rather than by an individual day’s peak temperature.
The articles say global temperature has increased by about 0.14°F per decade since 1880—a rate detail not specified in the summary.
The articles explicitly connect climate change with rising temperatures and increasingly frequent record heat.
Stacker analyzed more than a century of climate data to rank the hottest Octobers on record in 10 states since 1895. NOAA identified July 2026 as the hottest month ever recorded across the continental United States, signaling a broader warming trend that has pushed October temperatures to historic highs in states like Nevada, Louisiana, Florida, and Georgia.
The rankings measure each October by its statewide average temperature rather than individual daily peaks. NCEI data shows Earth's temperature has risen approximately 2°F since 1880, a warming trend that climate scientists attribute directly to ongoing climate change.
Stacker examined state average temperature data spanning 131 years to identify the warmest Octobers in Nevada, Louisiana, Minnesota, Massachusetts, Missouri, Georgia, Florida, Colorado, Delaware, and Alabama. Each state's ranking includes monthly averages, statewide highs, lows, and precipitation totals. NCEI provided the underlying climate records that made these rankings possible.
The continental United States experienced its hottest month on record in July 2026, according to NOAA. This record-breaking month underscores a broader warming pattern affecting autumn temperatures across the country. The milestone highlights how climate change is pushing seasonal averages to new extremes.
Earth's average temperature has climbed roughly 2°F since 1880, according to climate data. This warming occurs at a rate of approximately 0.14°F per decade. NOAA researchers connect this consistent warming trend directly to climate change and its effects on seasonal weather patterns across North America.
Rising October temperatures in ten states demonstrate how climate change reshapes seasonal weather. Stacker's analysis shows that record-breaking autumn heat is now common across diverse regions—from the desert Southwest to the humid Southeast. This pattern signals that extreme temperatures once considered rare are becoming increasingly frequent.
