Hi Bel, yes you can sunbathe in july but plenty of high factor cream(35) i used.
Drink masses of water all the time.dont have your air conditioning in the room too high as its not good for you.
Take re-hydration sachets in case you get an upset tummy(i had it for 3 days)
Not a good idea to go topless(no offence,but in case you normally do) as it is a muslim country and we should respect that.
Where abouts are you staying?
Just one more thing if you care about animals please dont book a swim with dolphins as they are not kept in proper conditions and do suffer.
