An archaic or dialectal term possibly referring to dune air, coastal wind, or a specific regional geographical or meteorological phenomenon (exact meaning uncertain).
Possibly from 'dune' (a sand hill) + 'air' (atmosphere), creating a compound word, though historical usage is obscure and the term is extremely rare in recorded English.
Words like 'dunair' highlight how English constantly creates new compounds when needed—'dune air' is such a specific image that it might have been useful to coastal communities, but most such terms fade from use.
