Not a cloud in the sky of Cape Town

"Those spilling clouds appear to vanish when that moist, cool air crashes into the warm air lower down the mountain. “If cloudy air is forced downward, like we see in the video, the air warms and the small water droplets evaporate back into invisible water vapor in the air,” he says. “So, the reason the clouds all seem to disappear is because the cloud droplets are evaporating as the air sinks and warms. The bottom of the clouds, in this case, is simply the point at which the cloud droplets have evaporated.”" -https://www.google.co.za/amp/s/www.inverse.com/amp/article/46354-table-mountain-cape-town-clouds
