Dyngjujökull moving many times faster than usual
A surge appears underway at Dyngjujökull, with GPS data showing the glacier moving at roughly 150 meters per year since early July—many times its normal speed. Experts note Dyngjujökull typically experiences multi‑year surges every 20–30 years, with the last occurring in 1998–2000.

Glacier retreated about 200 meters
Vestari Hagafellsjökull, on the south side of Langjökull, has retreated about 200 meters since 2023, according to a preliminary glacier-terminus survey conducted on 20 September 2025. Since 2009 the glacier has receded roughly 973 meters through 2023, with accelerated retreat likely tied to this summer’s warmth.

Flowers bloom again in an unusually warm November
Kale is sprouting even though it's mid-November.  Eucalyptus, rock rose, and Lenten roses don’t seem to be in the mood for winter, as they still wear their summer colors of green and red.

Glacial flooding continues in the Grímsvötn area
The flooding started yesterday in the Grímsvötn volcano area. The water flow at the source of the discharge reaches 300 cubic metres per second. The jökulhlaup is expected to last about 24 hours, which is how long the water takes to get to the Gígjukvísl canal on Road 1.

Good, though late, berry picking season
The berry picking promises to be good all over Iceland this year, even though it is starting late, due to the cool, wet summer. Arna, the lactose-free dairy company based in Bolungarvík, has already received a tonne of wild bilberries, which will be used in yoghurt for sale in shops all over Iceland.

Bacterial Infection Brucella Canis Suspected in Dogs in Iceland
The Icelandic Food and Veterinary Authority (MAST) has reason to suspect that a bacterial disease called Brucella canis has been found in dogs in Iceland. RÚV reports that Bruncella canis can—in very rare instances—be transmitted from dogs to humans, with young children, pregnant, and immunocompromised people at the greatest risk of serious infection.

Glacial Outburst Flood Will Likely Peak on Sunday
The glacial outburst flood, or jökulhlaup, which started when the ice sheet in the Grímsvötn volcano beneath Vatnajökull glacier began to melt 11 days ago, is predicted to reach its peak on Sunday. At time of writing, the Icelandic Road and Coastal Administration does not believe that the runoff will affect traffic on Route 1 […]

Earthquake at Bárðarbunga Caldera
Saturday’s incident is notable as Bárðarbunga, a stratovolcano located underneath Iceland’s largest glacier, Vatnajökull, is the second largest volcano on the island. Geophysicist Páll Einarsson told reporters, however, that the powerful earthquakes underneath the volcano this summer were likely due to land rise and that an eruption did not appear to be imminent.

Warmest July on record in north and east
This July was the warmest on record in nearly all of North and East Iceland. The average temperature was above 14°C at several weather stations, and no average monthly temperature in Iceland is ever known to have been higher.

Continued river warnings in north

The winter so far has seen very little snow in Iceland. December snowfall was well below average in both Reykjavík and Akureyri. Meteorologist Elín Björk Jónasdóttir says it has been one of the least white winters in living memory so far.

Bleeding tar makes road travel hazardous
Vegagerðin (the Road and Coastal Administration) is encouraging people to postpone journeys on Route 1 in the west and northwest of the country due to significant amounts of tar bleeding from the road surface and causing considerable danger and damage to vehicles. Clumps of tar collect and harden on the tyres of passing vehicles, making driving treacherous. Chunks fly off and have been causing some serious damage.

Surprise flood kills salmon in West Iceland
A jökulhlaup flood struck West Iceland’s Hvítá river in the early hours of Tuesday morning when water from a lagoon by the Langjökull glacier suddenly broke a new path and flowed in a different direction. Thick glacial mud now coats the river banks, and much of Borgarfjörður fjord.

43,000 litres of milk went to waste in the storm
The severe storm that hit Iceland last week had a major impact on farmers—largely because of power cuts and closed roads. Dairy farmers could not milk their cows during power cuts, and they could not refrigerate the milk that had been collected before the power went off. MS Iceland Dairies received 43,000 fewer litres of milk from farms last week than the week before.
