Temperatures are expected to get a little warmer on Wednesday, the National Centre of Meteorology said.
Abu Dhabi could experience anything up to 40°C with Dubai fractionally lower at 39°C.
A wider difference is forecast in humidity levels. The NCM predicts Abu Dhabi could get up to 85 per cent while Dubai's upper limit is given as 70 per cent.
Uninterrupted sun during the day is on the cards but come evening there is a slight chance of cloud formation to the east.
Mist is forecast for Thursday morning, although whether it will be enough to cause a traffic jam, as it did on Tuesday morning on the E11 highway in Dubai, remains to be seen.
