Hi Priscilla
It depends where you are moving from and what kind of weather conditions you are used to also which part of Jordan you will be staying in. I'm used to the wet and windy British weather with mild summers, so I find that over in Amman can be very hot and energy zapping. Not forgetting the occasional dust storms which are horrible, the stuff gets everywhere, so be prepared to do a lot of dusting.
If you like the hotter climate, then i'm sure you will really enjoy the weather, right now it has been around 32 C - 36 C in central Amman, last year was really hot in July at around 44 C.
I tend to stay indoors as much as possible during the day and try and get out to the shops etc later in the evening, the cons being everyone has the same idea so the roads are terrible.
Hope you have a good experience when you come over.
