So....you think you have it bad at work?
Today was brutal. Last week and the week before had days even worse. heat index's one day were 117 degrees.
Now some people might say "oh ya well the middle east gets up to 120-something everyday!" Well they DO NOT HAVE a heat index there (usually). Dew points are usually low enough they are negligible. Here our dew points have been 70+ degrees, even touching 80 degrees one day.
Then others still "well I worked inside a house without A/C". Or the somewhat common "my car doesn't have a/c" blah blah blah
Check these pictures out. Today only topped out at 94 degrees IIRC which has been faily common as of late. However that is just the official temperature reading taken at the airport. Temperatures at other places in the city will vary.
I took some thermal measurements with a infrared laser thermometer accurate to within +/- 2 degrees.
Here You can see this piece of cardboard laying on the patio of the construction site we are at. Its sitting in the sun and the temperature is 140.3 degrees F.
Here is a quick shot of the stone patio itself. Temperature readings were anywhere between 125-140 degrees depending on where you took it. This is what were walking around on all day by the way.
Want to grab that hammer-drill? Better think twice about it as the handle is 137.7 degrees F.
Here's the hottub we helped install early this morning. Shaded all day. That's right...111.9 degrees in the shade on this patio.
Want to use that circular saw? Be prepared to wear a glove or endure some pain. 135.3 degrees F.
So at 111.9 degrees in the shade (where the heat index is measured) with a dew point of 70 (which was our dew point at the time these pictures were taken) gives a heat index value of about 122 degrees. Since the heat index is calculated in the shade, add at least another 10-15 degrees for how it feels when your in direct sunlight. Another thing to think about is that this patio we've been working on has wind breaks on all four sides. Meaning we don't get that nice cool (or hot) breeze.
At this heat level, you sweat so much that you really have to constantly be drinking. I can easily go through a gallon worth of water/gatorade/etc in the afternoon.
