What would you expect the temperature to be at a height of 500 meters up the mountain?

At a height of 500 meters up a mountain, the temperature is generally expected to be cooler than at sea level. As a rule of thumb, the temperature decreases by approximately 6.5 degrees Celsius for every 1,000 meters of elevation gain in the troposphere. Therefore, if the base temperature at sea level is known, you can estimate a drop of about 3.25 degrees Celsius at 500 meters. However, local factors such as weather conditions and geographical features can also influence the actual temperature.
