Humidity will rise to 95 per cent over the UAE on Tuesday.
Partly cloudy and hazy weather is expected, with some clouds over some eastern and southern areas, the National Centre of Meteorology and Seismology said.
Winds will be light to moderate in general and freshening at times, causing dust and sand to blow over some exposed areas by noon.
Temperatures will rise gradually and will vary from 28°C to 37°C along the coast, 27°C to 43°C inland and 27°C to 35°C in the mountains, the weather bureau said.
Relative humidity will increase overnight and early Wednesday morning over some coastal and internal areas, leading to a chance of fog across the country.
The maximum humidity will range between 70 to 95 per cent across coastal areas, between 65 to 90 per cent in internal regions and 30 to 50 per cent in the mountains, the bureau said.
Mist formed during the early morning over Al Ruwais Road and Al Minhad and there was fog over Liwa.
Conditions will be moderate in the Arabian Gulf and Oman Sea.
