I am wondering a word to express the daily temperature values between. For example, I would like to describe hot/warm days with temperature > 30 C and the days in range 1-10 C. The range of my temperature values are 1 to 40 C. I have thought to express as
- very hot/warm days (for temperature > 30 C)
- cold days (for temperature 1-10 C)
Would you please suggest any other suitable phrases to express it.
