There are many websites online provide the speed of sound in air as a function of temperature.

Try this one:

The most accurate formula is

Speed of sound = sqrt[(gamma)*R*T]

where T is the Kelvin temperatuere and gamma is the specific heat ratio, which is 1.4 for dry air. R' is the molar gas constant divided by the molecular weight of air .
