The global temperature for June 2020 was 0.79C based on my spherical triangulation method. Here are the monthly results based on the latest GHCN-V4 and HadSST3 data as compared to those from original V3C station data.

The temperature peaked in February at 1.1C and has since been falling. The Northern Hemisphere also shows a notable hotspot across Siberia as shown below.

Half way through 2020 we can also calculate the annual temperature anomaly. This gives an average value for the first 6 months of 0.98C. For comparison I also show the results based on HadCRUT4.6 up to 2019. CRUTEM4 station data is not yet available for June 2020.

2020 looks set to become the warmest year to date, although the monthly trend still appears to be dropping.
