Foggy mornings are quite normal in the UAE during late September, October, and possibly early November. Most likely places for fog are interior areas, inland areas of coastal cities epsecially the highways between Abu Dhabi and Dubai. Immediate coastlines tend to be less foggy. Humid and calm nights can be an indicator of a foggy morning. As overnights temperatures get slightly cooler, and dew points still high, the chance of air parcels condensing becomes higher during this time of the year.
