Ohhh that makes sense. And since they are so close to water, there is always an amount of humidity in the air too I suppose.

Thank you for the explanation!

Dubai is on the coast too, though. So there's something else going on. My guess is the dry sand might be a moisture sink and vegetation itself often puts out and collects a lot of humidity, but there's not as much around in Dubai.
