Imagine I was measuring the temperature in your home. I measured above your grill. Is that a good average for your home temperature?

It doesn't say highest average measurement, it says highest recorded temperature. Plus, there is a 70.7 average measurement listed as well.

You're right, it doesn't need to be an average. Meteorologists are interested in outdoor air temperature in the shade, away from local disturbances like buildings and the ground. That way it's not influenced by uninteresting local effects like the color of the walls, direct solar heating (affected by the properties of the thermometer itself) or somebody turning the oven on.

That 70.7 degrees from the satellite was ground temperature, not air temperature, so it can't be compared.

I once set my oven to 350F, does that mean my house holds the record?

Did you measure it from a satellite?

Not even close. What do you reckon the highest temperature was achieved in a house?

I heard the tungsten filament in old-fashioned light bulbs can reach 2800K.

And LEDs can now reach 5000K :)

That's colour temperature, not actual temperature.

A tungsten filament can reach 4500 degrees Fahrenheit

Forest fires have burnt houses. That's visible from space too.
