At a 19 inch radius from the APU exhaust, the temperature and wind velocity are approximately:

Explanation:
At about 19 inches from the APU exhaust, the plume has expanded and mixed with ambient air, so you’ll see a hot but not extreme temperature and a modest wind effect. The temperature reads roughly 259–295 degrees Fahrenheit, and the wind velocity is around 24 miles per hour. Closer in or from a more powerful source would push temperatures higher and speeds much higher, but at this distance the plume has cooled and slowed enough to yield these moderate values.
