State-by-State Lists Name the Wettest Septembers in U.S. Records Since 1895

Overview

• Stacker compiled state-by-state rankings from NCEI monthly totals and local outlets republished those lists on Thursday and Friday, confirming each state's wettest September since 1895.
• Each entry ranks months by total precipitation and also reports statewide monthly high and low temperatures plus the state's average temperature for that September.
• Examples from the lists include Colorado's top September in 2013 with 3.88 inches, Texas's top September in 2018 with 6.71 inches, and California's top September in 1918 with 1.55 inches.
• NOAA's mid-2026 analysis, cited alongside the compilations, frames recent clusters of record months within long-term U.S. warming and a strengthening El Niño but does not change the ranking method.
• The lists are meant for historical comparison rather than causal proof, and NOAA's El Niño warning means communities and water managers should watch for a higher chance of extreme months into the coming autumn and winter.
