WEATHER in Iceland 2025>

After a warm May, Iceland has slammed into June with a full-blown winter relapse.

Snow, gale-force northerly winds, and near-zero visibility have gripped the country —particularly the mountains— prompting authorities to issue weather warnings and initiate a public safety “uncertainty phase.”

Roads are already vanishing in the whiteout, and travelers are being told to stay put.

At Mt Þverárfjall and along Siglufjörður Road, conditions look more like January than early summer.

Many of Reykjavík’s trees began changing color this June — not from autumn, of course, but from cold shock.

A sharp drop in temperatures at the start of the month scorched newly emerged leaves, especially on north-facing sides. By late June, the visual damage was clear: half-withered trees across the capital city.

Icelandic meteorologist Trausti Jónsson confirmed this was no ordinary chill. “The first 20 days of June averaged just 7.8C (46F),” he wrote, calling it the coldest start to June in Reykjavík since at least 2001. That’s 1.7C below the 1991–2020 baseline.

Looking at the record books ( which date back to 1873), only 20 Junes have been colder. And even among those, the variation is tight — the all-time low sits at 6.6C (44F) from

Iceland just recorded a colder June than May.

According to the Icelandic Meteorological Office, almost all weather stations reported below-average temperatures for June.

Reykjavík averaged 8.8C (47.8F), one degree below the 1991–2020 norm, with Akureyri dropping to 8.1C (46.6F), a full 1.5C (2.7F) below the norm.

Iceland's “summer” is running cold, wet, and well off-script.

Reykjavik awoke on October 28 to its heaviest October snowfall since records began in 1921.

The Icelandic Meteorological Office confirmed 27 cm (10.6 in) of snow measured at its Reykjavík station that morning, surpassing the previous October record of 15 cm (5.9 in) set more than a century ago.



By midday, accumulations had reportedly exceeded 30 cm (a foot) across parts of the capital, turning the city into a standstill.

Roads were impassable, buses were halted or delayed, and crews focused only on keeping main routes open as side streets disappeared under drifting snow.




An ‘orange weather warning’ was issued with authorities advising residents to stay indoors.

Morgunblaðið reported that the harbor froze and that the city’s snow-clearing capacity was “quickly overwhelmed.”



Freezing harbor.

Such heavy snow is exceptional for October, when Reykjavík typically sees only a trace or two.

Spare a thought for the three mosquitoes found just north of the city.
