November global surface TempLS up 0.06°C from October.

The TempLS FEM anomaly (1961-90 base) was 1.091°C in November, up from 1.031°C in October. It was the thirdd warmest November in the record, behind 2023 and 2024.

As in recent months, GHCN has gaps in coverage, which I have partly filled with JMA data. The critical point is cover of land stations outside US. This time I have 2529.

Here is the corresponding stacked graph. 2025 YTD stands in second place, behind 2024 but just ahead of 2023 and it would take a very cold December to change that.


Here is the temperature map, using the FEM-based map of anomalies. Use the arrows to see different 2D projections.






As always, the 3D globe map gives better detail. There are more graphs and a station map in the ongoing report which is updated daily.
