My top tip? Don't forget a pair of sunnies, and wear them if you ever have to nip outside during the day. Because of the white-ish sand and concrete paths, the reflection of the sun is blinding, especially if you've only just woken up
During Jul/aug, the top temps are (given by the metman, truthfully or not) around 48 degrees. it's probably more, but jets tend to hit their operational limit at 50 degrees!
And get down to Doha - cut price gym facilities in the hotels, Friday brunches, the souq, nice restaurants, a bit of shopping....... it's not really Basra, so I don't think you need to worry. Except about the spams. And Chuck Norris...........
