Direct sun is a reality to many folks, and the "95 feels like 97" is not nearly so meaningful if you are unlucky enough to spend time outdoors. It would be very meaningful to add "Direct Sun" to our weather. 95 degrees is mild in the shade feels fairly mild in the Texas summer, but can translate to 110 or 115 if you are forced to be in the sun. I say this is an important weather item that has been missing from our local weather.
I agree.

In Perth and southwestern Australia
a shade temperature of 97 F (37 C) can possibly feel milder than 77 F (26 C) out in the midday sun,
walking on sand dunes or somewhere like an unshaded large parking lot.
You can feel it in how quickly you get dehydrated.

I agree that the direct sun factor is important in determining comfort, but my understanding is that there isn't a standard formula for estimating it. According to weather sites that I've looked at, the air temperature is always the same in the shade versus the sun (for a given location) but a thermometer placed in the sun will read much higher because its components absorb the incoming radiation and convert it into heat energy. This is the same thing that happens with your skin/clothing, but any formula you could apply to the materials in the thermometer would not be valid for such radically different substances.

AccuWeather includes a direct sun factor in their RealFeel index but they don't tell you the basis for the formula (it's proprietary information). And it probably has nothing to do with sun vs. shade placement of thermometers.

I have one question that what is the effect of the soil temperature three feet below the earth level.
If the surface temperature on surface is 47 degree Celsius under shade then what would it be three feet below

You can compare room temp without AC

Sun is a important heat component in Indonesia, maybe because of the high (tropical) sun angle pretty much nobody here say a cloudy (or even a few clouds, but blocking the sun) day, even with no rain and humid 85-90F celcius to be "warm", but like in Bromo/Dieng highland people say "hot in the day" due to the very strong sun despite of it only being 50-60F with 45-50F dewpoint.

you can notice it by comparing room temperature without AC. virtually no difference between Bandung and Pekanbaru despite Bandung averages 4-5C cooler

i barely felt cooler at Lembang, 10am 21C with clear skies than Pekanbaru's clear skies with 31C.

I wonder what the thermometer would read in a sunny Vostok Station day (if you were to put it in the sun).
