Northeasterly or variable winds 3-8 m/s.
Intermittent light rain or drizzle in the south and southeast. Scattered showers in other places. Possible fog along the north and east coast.
Calm variable winds tomorrow. Intermittent rain in the west but showers elsewhere. Temperatures of 12 to 20 degrees C, warmest inland.
Forecast made 18.07.2025 18:34
Volcanic haze has formed under ideal conditions, light wind, humidity, and sunshine and has been observed widely, especially in the North and West of Iceland.
The weather forecast for the coming days indicates light winds, so volcanic haze may continue to be noticeable in some areas.

Eruption started on Sundhnúksgígaröð NE of Stóra Skógfell at 03:54 the 16th of July. The eruption is ongoing, but its activity and tremor have decreased. The main activity is concentrated around the center of the fissure that opened on July 16th. More Info.
Volcanic haze covers the Western and Northern parts of Iceland. Forecasts predict ongoing pollution over the weekend. Sensitive individuals should stay inside and babies should not sleep outside. more info.

Earthquake activity throughout the country is described in a weekly summary that is written by a Natural Hazard Specialist. The weekly summary is published on the web every Tuesday. It covers the activity of the previous week in all seismic areas and volcanic systems in the country. If earthquake swarms are ongoing or significant events such as larger earthquakes have occurred during the week, they are specifically discussed. More

Increased run-off from glaciers is expected today and in the coming days due to warm temperatures. Travelers are advised to show caution around glacial rivers and to keep in mind that fords and rivers can become impassable.
Due to malfunction we have turned off the service publishing hydrological data on the map. Instead see the data using our Real-time monitoring system.

The hazard assessment map has been updated. The eruptive fissure at Sundhnúksgígaröð has lengthened while lava flow has decreased. Seismic activity and tremor have declined, but gas pollution and wildfires remain ongoing.

Uplift and earthquake activity are ongoing in the Svartsengi area, with stable activity levels in recent weeks.
No substantial changes have been detected in measurements that would prompt a reassessment of the hazard level. However, continued magma accumulation could increase the likelihood of a magma intrusion or volcanic eruption in the coming autumn.
The flood is subsiding, and water level and conductivity are now approaching normal values in Skálm.
The flood reached its peak the night before last. IMO´s specialists continue to observe the area
Read moreIn May 2025, an unusually intense heatwave struck Iceland and eastern Greenland, breaking numerous temperature records. On 15 May, Iceland's national May temperature record was set at 26.6°C at Egilsstaðir Airport, with several locations recording temperatures up to 13°C above the monthly average.
A new international analysis by the World Weather Attribution group shows that human-induced climate change made this heatwave around 40 times more likely and, on average, three degrees Celsius hotter than it would have been without global warming. The study also suggests that if global temperatures rise by 2.6°C, such heatwaves could become at least twice as frequent and two degrees hotter.

days.
May temperature records were repeatedly broken at weather stations across the country.
A new national May temperature record of 26.6°C was set at Egilsstaðir Airport on May 15th.
