What do you wish you had known about this particular city/country before moving there?
I wish I would have known how hot it gets in the summer and how much that can impact your life. There are about 5 months out of the year where it is very unpleasant to be outside even in the early morning or evening. June, July, August, September you can expect temperatures of 100+ degrees every day and during the summer it's not unusual to have stretches of time where it is 110+ degrees every single day. The other 6-7 months out of the year are lovely but be prepared not to want to spend any time outside from May through September.
I also wish I would have known how expensive it is to live in Dubai. If you are prone to going out to different restaurants, night life etc. you can expect to pay prices on par with New York City which makes it harder to save money in Dubai, even with a cost of living allowance. - Dec 2016
