That's in the shadows, right?
On the other hand an object in sunlight will have temperature that has very complex relationship with a lot of parameters including shape of the object or windspeed.
Further, the object will not come into equilibrium and will show a gradient of temperature meaning the readout will depend on where you measure.
I suppose the air (the wind) tends to be colder than objects in the sun, since most sunshine pass straight through the air.
A way to investigate this, is to step barefoot on flat black stones, in the summer sunshine
* under a tent, i.e. in the shadow and sheltered from direct wind: commonly used and correspond to the temperature of the air;
* wet bulb: more recently under attention, correspond to the effect of cooling by evaporation similar to what a healthy human body does. Wet-bulb often gives much lower number in a dry heat and is more significant for human survival. I’ve read that 32ºC or 88ºF are likely were prolonged exposure lead to adverse health but don’t quote me on that.
Also measuring air temperature is easier and more practical as it is just enough to measure temperature of an object that comes into equilibrium with air.
The third one is radiative equilibrium. You could achieve that in a solar furnace, the object won't get hotter than the black body temperature of sunlight, which is ~5800K.
