Question: How hot is the pavement (sidewalk) on a 90-95 degree day?
Anyways, I am wondering if anyone knows about how hot the temperatures were on the pavement here in Arizona today where it maintained a solid 90 degrees for the majority of the day. Needless to say, I have blisters and what I think are probably a few mild burns. I know this seems like a dumb question. Going into it I knew it probably wasn't the best idea, so you don't have to tell me that. I would just really appreciate any answers if anybody happens to know! Thank you so much!
Answers:
The ultimate temperature depends on the environmental conditions of the day you test. Wind, outside temp, humidity, latitude, cloud cover, orientation to the sun ...all effect the ultimate temperature.
Look at this website and it says the solar reflectance for old asphalt is about .10, which means 90% of the infrared of the sun heat is being absorbed by the asphalt. With the sun emitting approximately 1000 watts per square meter at earth's surface it wouldn't seem to unlikely to achieve upwards of 150 F on windless, warm, sunny days.
