The year 2024 was remarkably cold compared to temperatures of this century. The national average temperature was 0.8 degrees below the 1991 to 2020 mean, and it was the coldest year since 1998. Lowest relative temperature was inland in the North, while it was warmer along the southern coast. The summer was wet across the entire country, but other months of the year were relatively dry. Overall, the year was drier than average in the eastern, southern, and southwestern parts of the country, but wetter than average in the North and West, which experienced heavy rain during summer. The sea level pressure was unusually low from June through August, and the summer was characterized by frequent low-pressure system passage and unfavourable weather. During other seasons, the weather was relatively calm, and annual mean seal level pressure and wind speed were around average.

The first phase of the Icelandic Meteorological Office's (IMO) new website was launched today. This marks the beginning of a major project aimed at renewing both the website and its entire technical infrastructure.

The new weather forecast website is available at https://gottvedur.is/en/. While the site is still in development, once the renewal of the current website is complete, the new weather pages will be moved to the domain vedur.is.
