my memory likewise was in the U.S , when I went to San Francisco and Las Vegas Between July 12th-July 23st this year, I remember arriving in Vegas and the temperature being 106F and it felt incredible getting off the plane.
then after going to San Francisco on a smaller aircraft, a few days later we drove back to vegas via yosemite national park where in the valley it was 100F and up in yosemite it was 66F,
then the next day (on sunday the 18th) after stopping in a town on the eastern sierra nevada, we drove to Death Valley which we knew was famous for it's very very hot summer weather in July, going down the valley was amazing, watching the temperature rise from 99F when we set on at 10:45am to 115F in the valley at 11:30
after a while we got out at furness creek at 1:20pm, the largest, lowest (at nearly -100bsl) and hottest settlement in Death Valley, the temperature was a staggering 122F (or 50C) and it was incredible B) , I was sweating but surprised at how well I coped with it and went for a walk until 2:45pm
then after driving back to Vegas and staying for 5 days there every single day was around or above 110F (44C) and amazingly some overnight lows were often not below 100F (37C), even when walking around at night Las Vegas feel like a large hairdryer,
also when we drove to the grand canyon there was a beast of a thunderstorm with fork lightning clearly visible on the mountains, and it tipped it down with rain and large hail too! the funniest thing was, despite the heat, I still wore me fleece most of the time to make it feel even hotter!
