The High Arctic has endured an extraordinary summer cold run, with DMI data showing record-low daily means on 36 of the 41 days from July 1 through August 10.
A full audit of DMI’s >80°N archive—comparing each 2026 date against the same calendar date in every available prior year back to 1958—leaves just five non-records: July 1, July 22, August 4, August 8 and August 10.
That means 88% of the period set a daily cold record.
The first streak ran for 20 consecutive days, from July 2 through July 21.
Another 12 straight records followed from July 23 through August 3.
July 26 was particularly notable, averaging -0.347C — the coldest July daily mean anywhere in the full DMI record.
August 9 came in at -0.590C — the lowest daily summer mean across the entire series (Jul 1 through Aug 10).
