## In brief

- October 2026 was the fourth warmest October in 132 years of recordkeeping for the contiguous 48 U.S. states, according to NOAA's National Centers for Environmental Prediction.
- The report came after July, August and September, plus March, were all reported as warm months, so the cooldown was described as microscopic at best.
- Floods affected several southern U.S. states during the month.

## Why it matters

The report adds to a run of warm months in 2026 and links the heat to flooding in the southern U.S., which matters for anyone tracking regional climate and flood risk.
