II va faire beau
"Il va faire beau" means it's going to be sunny. From "Il beau" alone, I know it say "It's beautiful" or "It's going to be beautiful out" but I don't understand how "Il va faire beau" makes sense. How does "faire" come into play but not "etre"?
Faire in French is used that way to refer to weather:
Il fait chaud - The weather's hot
Il fait froid - The weather's cold
Il fait beau - The weather's nice
Il va faire beau (future tense) - The weather will be nice
There are many such cases where avoir or faire are used when English uses be, that's because French and English are different languages and structure things differently.
So many expressions use "faire" and we just have to learn them: https://www.thoughtco.com/french-expressions-with-faire-1368674
