we did this in Lanzarote last year
someone recommended we get a taxi back from town because it was so hot and we laughed at them thinking they were fools and we were tough people who could walk in a bit of sun. We didn't realise we had to go back a different way and it was 2 miles in near African sunshine with no wind so we found a supermarket and poured bottles of water over our head

On a serious note, quite a few people die from similar things.
People from the UK don't quite realise how strong that sun can be.
