Whats the difference between Il y a, est, C'est, Il fait
I'm like 75% sure you must use fait when using weather but now il y a is also used for weather so when must i use each of these.
Il fait + adjective
Il fait froid It is cold
Il fait beau It is nice
Il y a + noun
Il y a du vent It is windy
(vent is a noun, but in English we use the adjective windy)
Il + verb
Il pleut It is raining
Here is a link to the Tips & Notes for weather, in case your French course does not have TIps & Notes: https://forum.duolingo.com/comment/29959455
If you don't know about Tips & Notes, when you click into a skill set (round circle) if you see a light bulb icon, click it! The Tips & Notes for French (from English) are exceptional.
"Il y a" means "there are" or "there is". For weather, you would use "il y a" to say "there are clouds" (i.e. "it is cloudy") or "there is wind" (i.e. "it is windy"). For most other weather-related phrases you would use "il fait".
