July weather forecast and Climate
Dubai, United Arab Emirates

As the summer advances and the monsoon spreads northwards over India the lee low effect over southern Iran begins to weaken and pressure gradients become weak over the area. Land and sea breezes begin to dominate the flow and as the sea is still warming up thermal gradients can be strong with a moderate to fresh Northwesterly sea breeze most afternoons. The humidity can become extremely high at times producing severe stress. The combination of high temperatures and high humidity can make atmospheric conditions extremely unstable and summer thunderstorms are not uncommon. As in June these usually develop over the mountains in the East of the Emirate where the mountains act as elevated heat sources and where convergence often occurs. Sea breezes on the east coast force very humid air up the mountains where it combines late in the afternoon with Gulf coast sea breezes from the Northwest. Inland stations frequently report Towering Cumulus and Cumulonimbus with thunderstorms, squalls and dust or sandstorms. Mid and upper level easterly winds then help to propagate the storms towards the Gulf coast where they can occasionally affect Dubai, Sharjah and the northern Emirates. Mean maximum temperatures in July are typically around 41°C,Inland Stations being the hottest with expected maximums of 44°C and all time extremes around 49°C. Sea temperatures begin to become unpleasantly warm reaching 32-33°C.
