After a sticky start to the week, Dubai and Abu Dhabi will continue to see high levels of air humidity on Wednesday, hitting as high as 90 per cent in some parts of the UAE.
The weather will mainly be sunny, with some cloud in the afternoon, especially eastwards, the National Centre of Meteorology forecasted.
Top temperatures could hit 40°C in Dubai and 43°C in Abu Dhabi, as temperatures rise from Tuesday.
Moderate westerly to northwesterly winds will likely cause dust storms across the country, the weather bureau said.
It will be rough in the Arabian Gulf and slight to moderate in the Sea of Oman.
