That 48C measurement widely quoted was a surface temperature, not the standard 2m above ground.

I assume not many phones are placed 2m above ground though, although not on the surface either, so the measurement should be only needed for getting an idea about the heat.

  It’s probably even warmer inside a pocket.

    If it's hot enough outside, at some point the phone will start using your body as a heat sink. So I guess it'd be warmer, until it's cooler, haha.

  Occasionally I do put my phone down on surfaces. Sure, elevated surfaces like retaining walls, outdoor tables, car dashboards, etc., but I'd expect those to behave a lot more like the surfaces in the satellite image than like circulating air 2m above ground.

> not the standard 2m above ground you made me think of an experiment i did (1.83m tall) in the foothills at higher elevation north of Phoenix last week: i tried walking barefoot on white concrete sidewalk at noon, for about 5 meters. The UV is extremely high here, and temps have been over 110F (around mid 40s celsius) for weeks a few hundred feet lower in elevation. It's scaldingly hot at the surface, while up around 2m up it's hot but MUCH less hot. Something it keep in mind with dogs, obviously. It's basically dawn and after dusk for walking here for another few weeks.

  There’s a huge difference between surface temperature directly in the sun and not. The air temperatures in weather reports are measured in the shade. The summer sun can literally cook eggs in some hotter regions.
