"chaud" is hot in French. Il fait chaud = it's hot.
un temps chaud
It means "you are very cute and hot".However, this is not proper french as chaud means hot as in 'the weather is hot' or 'my tea is hot'- it can not be used to describe someone.
It is hot is "il fait chaud" (the weather is hot, it is hot outside, etc..) or "c'est chaud" (about your food for instance)
Le temps est chaud au printemps.
A big difference is in how one describes (current) weather conditions. In English one says: "It [the weather] is beautiful." "It is cold." "It is hot." etc. In French one does not use the verb "to be" in this case; one uses the verb "faire," which normally translates as "to do" or "to make." Examples: It [the weather] is beautiful --> Il fait beau. It is cold --> Il fait froid. It is hot --> Il fait chaud.
