The
TempLS FEM anomaly (1961-90 base) was 0.859°C in April, down from 1.017°C in March. It was still the fourth warmest April in the record, and the second warmest month since October 2021. The
NCEP/NCAR reanalysis base index fell even more by 0.332°C.
Almost all the world was warm, with cold spots just in Alaska, central Siberia down to India, and some of mid west USA. Nowhere was very warm, except a patch in Antarctica.
Here is the temperature map, using now the
FEM-based map of anomalies.
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.
