It’s going to be really hot the next few days – hot weather trivia

As of late July, we can honestly say that we’re experiencing the worst heat wave Chicago has seen since 2013. It’s hot out there! With temps in the 90s, coupled with high levels of humidity, it feels like the Chicago area is a giant sauna. The National Weather Service said that in the next couple of days, July 21 and July 22, we’ll see the heat index go past 100 F and they’ve issued a heat warning for the Chicagoland area, including Northbrook, which is where this link to the NWS’s warning is geotargeted. And for good measure, there’s also a thunderstorm warning in effect.

thermometer in the sky, the hot weatherSince we can’t avoid the hot weather over the next few days – here’s some trivia about high temps in Chicago and around the world.

Why does it feel hotter when it’s humid?

On dry days, sweat evaporates quickly, which means it also carries away heat faster. On humid days, when the air is already saturated with water, sweat evaporates more slowly. This explains why it feels so much hotter in high humidity conditions.

What is the hottest day Chicago has seen?

The hottest day on record for Chicago depends on who’s calculating, but by one account, it was July 23, 1934 when Midway Airport recorded a high for the day of 109 degrees.

Officially, the National Weather Service recorded the temperature at 105 on that day, a bit lower but still the highest official reading ever.

During the killer heat wave of 1995, the official high temperature was 104, although it reached 106 elsewhere in the city that day.

What is the hottest place on earth?

Death Valley, Calif.

Death Valley, Calif.

For nearly a century the Mediterranean city of El Azizia in northern Libya held the official title for having been the hottest place on Earth. However in 2012, after an investigation by the World Meteorological Organization, the title was awarded to Death Valley, California, where the temperature reached 134.06 degrees in 1913.

So let’s all be glad we’re not in Death Valley or that the weather in Chicago is not a repeat of 1934.
