Most of the GHCN V3 data is now in, and ERSST v4, and TempLS mesh (the new V3) shows a rise from 0.618 to 0.665°C, relative to a 1961-90 base period. TempLS grid rose from 0.674 to 0.711 °C. Usually the mesh weighted version is more likely to agree with GISS and the grid version with NOAA, though this time they both are similar.
The rise is somewhat at variance with the NCEP/NCAR index, which suggested a fairly cool month, although that is muddied somewhat by the May oddity when that index suggested more warming than TempLS mesh and GISS showed. Anyway the TempLS calc is certainly warm, and for TempLS grid, seems to be almost a record, falling just short of the 0.718°C for Feb 1998.
The warm places were western US and central Russia, with cold in Antarctica and the E Mediterranean, pretty much as indicated in the NCEP/NCAR report. As I mentioned in my previous post, you can get more detail in the regular WebGL map here, which shows the actual station anomalies with shading between.
There was a curious delay with the Canada data which slightly set back this report. The initial posted data was a duplicate (mostly) of May, and flagged as such, so TempLS rejected it. That seems to have been corrected, and now 4266 stations (incl SST cells) have reported, which is almost all that we can expect.
In other news, Arctic ice has held up well in the last month, but the last two days of JAXA show rising melt, and Neven says more heat is on the way.
