The speed of sound rises about 0.59 meters per second per degree Celsius

Evidence

Therefore, we can see that sound increases by about 0.59 ms−1 for each °C rise in ambient temperature, and this can have important consequences for the way in which sound propagates. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 91
