I think that’s what the guy kneeling down at the 27,9 C measurement is doing, recording the temperature of that spot.
My doubt does come in though with the street measurement. The asphalt is cooler than the sidewalk? What? Also, did he go out into the street to take the measurement and then run back? I guess if there were no cars around he could have, but that doesn’t seem like a low-traffic area. Just a few weird things about that one detail.
Asphalt has less heat retention capability than sidewalk bricks. The asphalt is venting more of its heat into the surroundings than the bricks are, which is why it’s cooler.
There’s also very little traffic on his side of the street – you’ll notice there are almost no cars on that side, so it’s more than likely he had ample time to get a temperature read on the asphalt before a car came along
