I took an Italian course in college in which we always used fa to describe the weather, like so:
"Che tempo fa?" (What's the whether like, or literally, what does it do/make)
Just a few examples of answers: "Fa bello!" (It's nice!) "Fa brutto!" (It's ugly/gloomy.) "Fa freddo." (It's cold.) "Fa piova." (It's raining, also just "piove" for "it rains.") So if you're talking about the whether with limpido (or perhaps chiaro), would "Fa chiaro oggi" be a better way of saying it?
Because this is not common English usage. A native speaker would not describe a day as 'limpid'. They would use 'clear'. Limpid is an adjective used to describe clear or unclouded water, and very occasionally the clear tones of a musical instrument. As a native English speaker I have never heard it used to describe the weather. Hope this helps.
I know someone below asked this, but I wanted to see if any native speakers could shed some light on the difference between "limpido" and "chiaro". For example, could you say "Oggi è un giorno chiaro" or would it have a slightly different meaning? If they are not interchangeable, some examples of how they would be used would be wonderful. Thanks!
