A term in the context of temperature meaning it's just at the border of warm and cool. It is not distinctly warm, but you are not feeling a chill. There are no strong winds or rain or anything like that. It is very mild.
It is an early May afternoon and I am going for a walk. There is a slight breeze. It was a frepid day.

Carayay: Hey, I was thinking of going for a walk at the park, do you want to come?
Dremequé: Sure it's pretty frepid, great walking weather, why not?
Carayay: Alright cool, see you there
