Yes , it's almost impossible to get good observing sky in summer, we usually go to Mahdha area in Oman in road to Hatta, we turn to right from last shell filing station, we travel on this road about 20KM to get good sky,
the nearest area I would recommend is the kalba road till you reach to 2nd bridge then take left turn on top of bridge and travel to about 2 KM or get down in between dunes and reasonable sky could be visible.
please feel free to contact us for any help my numbers are on first page, 050-6246172
