September weather forecast and Climate
Dubai, United Arab Emirates

As temperatures begin to fall after the height of the summer there is a sting in the tail for residents of coastal cities. Sea temperatures reach a peak at the end of August and it is therefore during this time that the potential for warm, humid air to be advected to the coast reaches a maximum. September is far from being the most humid month but it has the highest humidity of the hot summer months. For this reason September is extremely humid and is one of the months with a high occurrence of fog. Night time temperatures begin to drop into the upper 20’s °C and fog will often form in the early morning hours. Maximum temperatures can still occasionally reach extremes of 45°C with extreme minimum’s around 22°C. Sea temperatures begin to fall later in the month with the mean for the month of around 32°C.
