Weather that is nice to look at through a window but unpleasant to be out in.

Origin: The word 'gluggaveður' is a compound word in Icelandic, consisting of 'gluggi' meaning 'window' and 'veður' meaning 'weather'. The roots trace back to Old Norse, where 'gluggi' meant 'opening' or 'aperture' and 'veðr' referred to 'wind' or 'weather'.
Historical and Cultural Context: First used in Iceland during the medieval period, 'gluggaveður' described the frequent phenomenon of visually appealing weather that is deceptively harsh when experienced outside. This term reflects the Icelandic climate, where harsh weather conditions are common.
Evolution: While the individual components 'gluggi' and 'veður' have remained relatively stable in meaning, their combination into 'gluggaveður' captures a uniquely Icelandic experience. Cognates can be found in other Scandinavian languages for 'gluggi' and 'veður', such as 'vindue' (Danish for window) and 'väder' (Swedish for weather).
Modern Relevance: Today, 'gluggaveður' is widely recognized in Iceland and among Nordic language enthusiasts as a poetic term. It's used in everyday conversation to describe those sunny yet bitterly cold days typical in northern climates.

In Iceland, 'gluggaveður' is often used humorously to describe the unpredictable and extreme weather conditions that can change rapidly, making it a popular term in weather reports.
