The official record for the UAE’s highest ever temp — and remember these are recorded in the shade, by specialist calibrated equipment, so the Insta Story screenshots of your car’s thermometer don’t count Susan — was July 2002, an eye-sweating 52.1ºC (125.78ºF).
In terms of ‘feeling’ hot (not to mention hair-do integrity), humidity is important too. And care of its coastal location that’s something Dubai knows a lot about.
Disclaimer — gross scienc-y stuff inbound. When we’re warm, our bodies sweat as part of their inbuilt equilibrium mechanism. The energy exchange from the evaporation of that sweat is what cools us down.
When weather reports are telling us there are high levels of humidity in the air (like for example those figures of 90 per cent we looking down the barrel of in the high summer), it means that the air is saturated with moisture. This then leads to your sweat not being absorbed, and thus the body, your body, all of our bodies, remain uncooled. Pro tip: Avoid wearing grey. Or leather.
High humidity levels in combination with high temperatures are the reason ‘feels like’ indexes on weather apps can have a bit of a (quite literal) meltdown when looking at UAE weather.
Despite what it feels like in the 15 seconds between the air con of your home/work and the air con of your car/the Metro — when it comes to the hottest outright temperature on earth, Dubai is a heavyweight alright, but it isn’t the reigning champ.
The highest temp recognised by the World Meteorological Organisation (WMO), is 56.7C recorded in Death Valley on July 10, 1913.
