The Version 6.1 global average lower tropospheric temperature (LT) anomaly for July 2026 was +0.48 deg. C departure from the 1991-2020 mean, which is statistically unchanged from the June 2026 value of +0.46 deg. C.
The Version 6.1 global area-averaged linear temperature trend (January 1979 through July 2026) remains at +0.16 deg/ C/decade (+0.22 C/decade over land, +0.13 C/decade over oceans).
The following table lists various regional Version 6.1 LT departures from the 30-year (1991-2020) average for the last 31 months (record highs are in red).

The full UAH Global Temperature Report, along with the LT global gridpoint anomaly map for July, 2026 and a more detailed analysis by John Christy, should be available within the next several days here. John officially retired on July 1, 2026, but will continue working as a part-time employee of UAH.
The monthly anomalies for various regions for the four deep layers we monitor from satellites will be available in the next several days at the following locations:
