Weather in Surtsey 2020-2024

A new maximum air temperature record of 22.6°C was set on Surtsey, Iceland's southernmost island, on 14 July 2025, breaking the previous record of 18.6°C from 11 July 2023. This study analyzes weather data from 2020 to 2024, highlighting significant variations, including a notably cloudy and cool summer in 2022 and a winter (2022–2023) marked by alternating warm/windy and cold/calm months. The research also identified extreme sea level pressure records of 1050.4 hPa and 932.3 hPa on 28 March 2020 and 15 February 2020, respectively. While temperature and wind data were robust, precipitation measurements faced considerable failures. The study aims to provide insights useful for understanding ecological processes on the island, which serves as a scientific laboratory for flora and fauna development.
