SNIP: Data provided by the Copernicus Climate Change Service (C3S), implemented by the European Centre for Medium-Range Weather Forecasts on behalf of the European Union, show that the global-average temperature for June 2019 was also the highest on record for the month. It was about 0.1°C higher than that of the previous warmest June, in 2016, following a strong El Niño event.
The map of temperature anomalies highlights just how unseasonably warm the end of the month was. Compared to the average for the same five days during 1981-2010 (the standard 30-year climatological reference period), temperatures of 6-10°C above normal occurred over most of France and Germany, northern Spain, northern Italy, Switzerland, Austria, and the Czech Republic.
Looking at the temperature data from a longer-term perspective reveals the month to be even more unusual. Merging the latest C3S data with datasets that extend further back in time shows that the June 2019 European-average temperature was more than 3°C higher than the average for 1850-1900.
