HI,
The current weather is HOT and HUMID
tempratures upto beyond 40 deg centigrade.
Clothes - light colored, cotton, cap a must, sun glasses with UV protection.
For the first timers - the Big bus tour is a must, a visit to the dubai museum, wild wadi water park, ski dubai.
Night time - Go to madinat for a dinner, ample of pubs to hit.
And yes i know u would love to shop so all the shopping malls are gonna be on your hit list city center, mall of the emirates and ibn batuta are a must go.
Hmm thats what came to my mind:) people will add more.
