The High Arctic has just recorded its coldest summer in record books stretching back to 1958. Danish Meteorological Institute data show temperatures north of 80N averaged -0.91C across June, July and August 2026. June averaged -2.2C. July was essentially 0C. And August came in at -0.55C. The result has now been independently checked by the Arctic Monitoring and Assessment Program which downloaded DMI's full archive and repeated the comparison. It's finding: June was the coldest June in the series, July was the coldest July by 0.5C, and summer as a whole was the coldest since records began in 1958. In nearly seven decades of DMI data, no High Arctic summer has been colder.
