"Did it rain last night?" No, kids, that is called condensation.

The full blast of summer has arrived in the UAE, and with it has come humidity that leaves windows covered in water droplets when you wake up in the morning.

And spare a thought for people who wear glasses and find them steaming up as they move between the air-conditioned buildings and the damp outdoors.

My glasses are starting to fog up when I walk outside here in the UAE. That humidity hits you like a bag of hammers. Not complaining, just an observation. — Cody Sigel Combs (@CodyCombsNEWS) June 14, 2019

The sticky evenings and mornings are here to stay - certainly for this week, according to the National Centre of Meterology.

The weather forecaster said winds will help to freshen western areas as the day progresses on Saturday, but humidity in the east could remain between 70 and 90 per cent due to cloud cover.

Is 70 to 90 per cent humidity common in the UAE?

It is not unusual for humidity levels to reach 100 per cent in the Emirates.

When it does reach 100 per cent, it means the air is totally saturated with water vapour and cannot hold any more - and it is time to take a spare t-shirt with you if you're going to be spending time outdoors.

Such conditions are largely caused by the warming of the seas, which increases evaporation, while hotter temperatures on land means the air absorbs more water. Areas around the coast are most affected.

Temperatures will be high, with Abu Dhabi and Dubai reaching between 40°C and 45°C. Al Ain and Liwa could reach 46°C, after topping 48°C last week. This is, however, slightly lower than Kuwait where the heat was reported to have topped 50°C.

Fog and mist made an appearance this morning over Abu Dhabi Airport and Al Maktoum International Airport in Dubai. Both the Arabian Gulf and Oman Sea will be slight to moderate.

Forecasters said there could be some respite by Tuesday with slightly lower temperatures, but otherwise the next few days will be hot, humid and dusty with wind speeds in some areas up to 40kph.
