Weather
Note that nube is feminine, which surprises some learners since weather nouns in Spanish have no consistent gender pattern. Its adjective form, nublado (cloudy), is masculine by default and does not change to match nube itself.
Worth knowing: in Latin American Spanish, weather involving wind is expressed with hacer rather than haber or estar. You say hace viento (it is windy), just as you say hace calor or hace frio for temperature.
