Hot enough for ya? September 2026 was hottest September ever in United States

 

Map and headline:  Yale Climate Connections, 10/9/2026

Jeff Masters and Bob Henson report:

 Global ocean surface temperatures were the warmest on record for September, while global land temperatures were the third-warmest. It was the third-warmest September on record for global temperatures estimated by satellite through the lowest few miles of the atmosphere (the lower troposphere). North America, Asia, and the Arctic recorded their warmest September on record; Oceania, its second-warmest; Africa and Europe, their fourth-warmest; and South America, its seventh-warmest. 

According to NCEI’s statistical analysis, there is a greater than 99.9% chance that 2026 will rank among the three warmest years on record, but only a 0.1% chance it will be the hottest year on record. However, this statistics-based product is not designed to explicitly take El Niño or La Niña events into account, so with a record-strong global-atmosphere-warming El Niño event in full swing, it’s quite possible that 2026 will be the hottest year on record.
