Thermal comfort is how comfortable you feel due to the temperature of the environment that you are in. Generally, if the temperature is too hot or too cold, you don't feel comfortable and this is known as thermal discomfort. Temperature is just one factor that can influence how comfortable you feel- things like how humid it is, how much air is moving, and how much clothing you are wearing can also affect how comfortable you feel. All these things together combine to create your thermal comfort.
