Answer 3

Hello there!
If I may join in... remember in Spanish the verb HACER is commnoly used to talk about weather.

The structure is:
HACE + a noun related to whether.

For example:
It's cold = *Hace frio.* ([literally] = "It does coldness.")
It's hot = *Hace calor.* ([literally] = "It does heat.")

Some vocabulary:
*frio* is "coldness"
*calor* is "heat"
*viento* is "wind"

Now, @Austin_15 , looking at the vocabulary above, can you guess how we say "It is windy"?

Hace...

Hope this helps!
