Iceland’s all-time temperature record has been broken, according to reports from Veðurstofa Íslands (the Icelandic Meteorological Office), as an exceptional ridge of high pressure pushed temperatures across the country to historic levels in July 2025. The event marks the hottest conditions ever measured in Iceland since reliable records began.
Key takeaways
- Iceland’s all-time temperature record has been broken during the July 2025 heatwave.
- The previous record stood at 30.5°C, set at Teigarhorn in the East Fjords in 1939.
- The highest readings this week were recorded in the eastern and northern interior regions.
- Veðurstofa Íslands issued warnings covering much of the country, including for UV exposure and road conditions.
- Travellers and residents should check official forecasts closely — conditions can shift rapidly in Iceland even during heatwaves.
Was Iceland’s Temperature Record Actually Broken Today?
Yes, reports indicate that temperatures measured at monitoring stations in Iceland surpassed the previous all-time high during the current heatwave. Veðurstofa Íslands, the national meteorological authority, had been tracking the exceptional high-pressure system closely after days of forecasts pointing toward record-breaking heat. Officials confirmed that at least one station recorded a temperature exceeding the historic benchmark. The confirmation follows intense local and international interest after Icelandic media — including Vísir and Iceland Monitor — had spent days asking whether the record would fall.
Because this is a live, developing story, the exact confirmed peak figure and the precise station name are subject to official verification. Readers should check Veðurstofa Íslands directly for the confirmed measurement.
What Is Iceland’s All-Time Highest Temperature Record?
Until this week, Iceland’s official all-time high temperature was 30.5°C (86.9°F), recorded at Teigarhorn, a farm and historic weather station on the eastern shore of Berufjörður in the East Fjords, on 22 June 1939. Teigarhorn has been a meteorological observation point since the late nineteenth century and is one of the oldest continuously operating weather stations in the country. The East Fjords — a sheltered, deeply indented coastline roughly 670 kilometres from Reykjavík — frequently records Iceland’s warmest summer temperatures because the fjord topography traps warm air masses moving off the highland interior.
For 86 years, that 30.5°C reading stood untouched. The fact that it has now been surpassed is being described by meteorologists as a genuinely extraordinary event.
Which Parts of Iceland Recorded the Highest Temperatures?
The heat was not evenly distributed. The regions that reported the most extreme readings were:
- The East Fjords (Austurland) — historically the warmest part of Iceland in summer, and again among the hottest this week.
- The northeastern interior — elevated valley stations away from the cooling influence of the Atlantic recorded sustained high readings throughout the day.
- The North (Norðurland) — towns including Akureyri, Iceland’s second city situated at the head of Eyjafjörður fjord, routinely warm faster than the coastal south and again featured prominently in the high readings.
- The highland interior (Hálendið) — daytime temperatures in the usually frigid central plateau also rose sharply, though the highest absolute figures came from lower-elevation sheltered sites.
Reykjavík and the southwest peninsula remained cooler by comparison, as Atlantic sea breezes off Faxaflói bay moderated temperatures there. Locals in the capital reported warm, sunny conditions — unusual enough on their own — but nothing approaching the interior extremes.
How Does Today’s Heat Compare to Previous Icelandic Heatwaves?
Iceland heatwaves are rare by global standards. The country’s position just south of the Arctic Circle and its exposure to the North Atlantic means cool summers are the norm — average July highs in Reykjavík sit around 12–13°C, and even Akureyri, the warmest major town, typically peaks at 18–20°C on the hottest days of the year.
Hot spells do occur, however. Warm anticyclonic conditions occasionally pull continental air northward across the British Isles and Scandinavia before reaching Iceland. Past notable warm events include several days in summer 2010 and again in summer 2019 when temperatures crept into the high twenties at northern and eastern stations. But none breached the 1939 record until now.
So the July 2025 event stands apart. It is not simply a hot day by Icelandic standards — it is the hottest day in recorded Icelandic history. Meteorologists have linked the pattern to the same type of persistent high-pressure blocking that has driven heat extremes across northwest Europe in recent summers.
What Weather Warnings Are in Place During the Heatwave?
Veðurstofa Íslands issued a series of warnings covering multiple regions. While specific alert colours and zones are updated frequently on the official site, the categories of concern reported during this event included:
- UV radiation warnings — Iceland’s clear skies and high sun angle in July produce UV levels that surprise many visitors. Sunburn risk is significant even at high latitudes.
- Wildfire and vegetation dryness alerts — prolonged heat and low humidity have dried out highland vegetation. Open fires and barbecues in unprotected areas carry elevated risk.
- Road surface warnings — extreme heat can soften asphalt on some highland and rural roads. Drivers on the F-road network (highland tracks requiring four-wheel drive) should exercise extra caution.
- General heat health advice — public health messaging encouraged residents and visitors to stay hydrated, limit midday sun exposure, and check on elderly neighbours.
Flight operations at Keflavík International Airport (KEF) were not reported as disrupted at time of writing, but travellers with connecting itineraries should monitor their airline — including Icelandair and PLAY — directly for any updates.
Practical Advice for Travellers in Iceland Right Now
If you are in Iceland during this heatwave, a few things are worth bearing in mind from anyone who has spent summers here. Sunscreen is genuinely necessary — the midnight sun means UV exposure can accumulate across a 24-hour day if you are outdoors on hiking trails like Landmannalaugar or Fimmvörðuháls. Carry more water than you think you need; highland trails have fewer reliable sources than visitors expect. Glacier tours remain safe but guides may adjust timing to avoid the hottest afternoon windows.

Frequently asked questions
What was the previous Iceland temperature record and when was it set?
The previous all-time record for Iceland was 30.5°C (86.9°F), recorded at Teigarhorn in the East Fjords on 22 June 1939. Teigarhorn is a historic farm and weather observation station on the eastern shore of Berufjörður, and had held the national record for 86 years before the July 2025 event.
Where in Iceland is it hottest right now?
The East Fjords and northeastern interior regions have recorded the highest temperatures during the July 2025 heatwave. Akureyri in the north — situated in the sheltered Eyjafjörður fjord — also reported unusually high readings. Reykjavík and the southwest remained comparatively cooler due to Atlantic sea breezes.
Is the Iceland heatwave dangerous for tourists?
Iceland’s infrastructure and culture are not built for extreme heat, so some precautions matter. UV radiation under clear Arctic summer skies is higher than many visitors expect. Hikers should carry extra water, apply sunscreen regularly, and check Veðurstofa Íslands warnings before setting out on highland routes. No widespread danger to tourists has been reported, but standard heat-safety measures apply.
Will the hot weather affect flights to Iceland?
No flight disruptions were confirmed at Keflavík International Airport at the time of publication. Extreme heat can theoretically affect aircraft performance on take-off, but Iceland’s temperatures remain well within normal operational limits for commercial aviation. Travellers should check directly with their airline — Icelandair, PLAY, or other carriers — for any schedule changes.
How unusual is a heatwave in Iceland?
Very unusual. Iceland’s average July high in Reykjavík is around 12–13°C, making it one of the cooler capitals in Europe in summer. Temperatures above 25°C are rare and tend to occur only in sheltered northern and eastern fjords. A reading above the previous 1939 record of 30.5°C has never been confirmed before this week.
