Il y a des nuages=There are some clouds. C'est nuageux=It' cloudy. Is it correct?

yes its correctt

The question relates to lesson:"Talking about the weather - il y a"

yes i got it ...and in french textes i hv seen both versions so its correct ...for the weather yoy can use "il y a" and "c'est"

C'est correct.

Merci beaucoup Rhi et FISEHA.

Bonjour yellamaraju,

Indeed in French you can use both sentences, "C'est nuageux" and "Il y a des nuages", to express "It's cloudy" in a general way.
"Il y a des nuages " can also simply means "There are some clouds", like for example in the sentence "Il y a des nuages dans le ciel.".

Thanks Aurélie, It is amply clear. Thanks again

Can you say 'il fait nuageux' and if so is this more correct than 'c'est nuageux'?

Bonjour John !

Though it seems that some people use it, "il fait nuageux" isn't correct in French. You'll prefer "Le ciel est nuageux" or "Le temps est nuageux", or "C'est nuageux" :)

Bonne journée !
