Surely not in Ramadan period as that time rules regarding eating and drinking are very strict. However tourists are not much affected but respecting culture is must. You can visit any time of the year but Ramadan. Try to visit during Shopping festival time
Best Time to Travel to Dubai. A vacation trip to Dubai points towards sun, sand, beach and shopping. The best time to go to the scorching hot city is during its cooler months i.e. in between November and April, when the hot sun is at rest and cool with blowing winds during the evenings and night time.
so u can go right now go enjoy ,brother
