UAH v6.1 Global Temperature Update for January 2026: +0.35 deg. C

From Roy Spencer, PhD

February 3rd, 2026, by Roy W. Spencer, Ph. D.

The Version 6.1 global average lower tropospheric temperature (LT) anomaly for January 2026 was +0.35 deg. C departure from the 1991-2020 mean, up a little from the December 2025 value of +0.30 deg. C.

Graph showing UAH satellite-based temperature departures from the 1991-2020 average in degrees Celsius from 1970 to 2026, featuring blue data points and a red trend line. The January 2026 temperature departure is noted as +0.35 degrees Celsius.

The Version 6.1 global area-averaged linear temperature trend (January 1979 through January 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 25 months (record highs are in red).
