All of this will be about how quickly the air column inside the tubing heats up and cools down. The interesting thing is that the air coming out of your mouth has a pretty constant temperature irrespective of the room temperature. Therefore, the effect of room temperature on horn tuning is fairly limited, in that of the room is cool, your horn and the air inside will cool more quickly. That effect can be minimised by blowing a lungful of air down the horn towards the end of a longer rest so that the inside of the horn is more nearly at boy temperature when you make your next entry.
