Gluggaveður is a popular word on the net, perhaps because it has been promoted as one of a list of words in Icelandic that could be usefully borrowed into other languages. "'Window-weather' describes weather that 'is nice to look at through a window, but not nice to be out in.'”
The eth character (ð) is pronounced like a furry version of the English th, or, as Wikipedia has it: "In Icelandic, ð represents a (usually apical) voiced alveolar non-sibilant fricative ..." It is best to find an audible pronunciation online to get the idea.
The strange gods of Iceland bequeath her A magical shape-shiftng ether. Where fire burns on ice And fine views entice That the unwary find gluggaveður.
