Answer 1

As others mentioned, IR heat is part of the answer. Being outside you experience the warming effect of the Sun on the planet and the radiating heat from surfaces exposed to sunlight.

But also, if you are basing the outdoor temperature on info from a weather app or station, their temperature is always measured in the shade. Depending on the time of day, the temp in the shade is going to be dramatically cooler than the temp in direct sunlight where you may be standing.
