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).
Also, all 41 days ran below the DMI’s 1958–2002 average (for the respective date).
Yet another wintry blast is sweeping Patagonia this week, bringing renewed heavy snow to Argentina and severe freezes across southern Chile following the biting conditions of the past few weeks.
