Met Éireann has issued a status yellow fog warning for the majority of Ireland on Thursday morning, affecting visibility across Leinster, Cavan, Monaghan, and Munster until 9am.

Road users are being advised to exercise caution due to poor visibility conditions during the morning commute, with the fog expected to be particularly persistent along southern and eastern coastal areas.
The weather warning covers most of the country’s populated regions, including major cities and transport routes, making it particularly relevant for commuters and early morning travelers.
Despite the challenging start to the day, conditions are set to improve dramatically once the fog lifts. Met Éireann forecasts the development of long spells of summer sunshine as the morning progresses, transforming Thursday into what promises to be an exceptionally pleasant day.
The national weather service expects temperatures to climb significantly, reaching between 21 and 26 degrees across the country. These warm to very warm conditions will be accompanied by light to moderate southeast breezes, creating ideal summer weather conditions.
The contrast between the foggy start and sunny afternoon highlights the importance of adjusting driving behavior during the morning hours. Poor visibility can significantly impact road safety, particularly on motorways and rural routes where fog tends to be most dense.
The fog warning specifically targets the morning rush hour period, when traffic volumes are at their highest, making careful driving and reduced speeds essential for safety.
Once the early morning fog disperses, Thursday is shaping up to be one of the finest days of recent weeks. The combination of abundant sunshine and temperatures reaching the mid-twenties will provide ideal conditions for outdoor activities and al fresco dining.
The southeast breeze will help maintain comfortable conditions even as temperatures climb, preventing the day from becoming uncomfortably hot while still delivering genuine summer warmth.
The dramatic improvement from foggy start to sunny afternoon exemplifies Ireland’s changeable weather patterns, where morning conditions can be completely transformed within hours.
