Most GHCN data for February is now in - a few gaps like Greenland, Mexico, Peru. For TempLS mesh (report here) the anomaly average rose from 0.889°C to 1.085°C. January had dropped from December; but still, the February reading beat the previous record month of December by 0.115°C. TempLS grid had a similar rise, but from a lower January base.
This adds to the evidence that February was very warm indeed. The NCEP/NCAR index was up by a similar amount (0.175); the two satellite indices were up by about 0.3°C. Each, of course, highest in its record. I would expect comparable rises in the main surface indices (GISS, NOAA, HADCRUT). GISS, for example, could approach 1.3°C.
The heat was especially in a broad band from W Europe to E Siberia, with a branch down through China. Another branch from Alaska to US Midwest. I think the patterns around Canada/Greenland may change with more data coming in, with possible upside to the global total.
The breakdown plot shows heat almost everywhere, except for Antarctica. SST is very slightly down.
I'll show here the ENSO comparison with 1997/8. 2015/6 is similar in pattern to 1997/8, but nearly 0.5°C warmer. If the pattern continues, the peak warmth may continue till August or so. The plot is in the style of this post, which I'll update from time to time.
