During the night and very early morning, probably very little.

Evaporation often happens at night because of the temperature differences.

I'm not sure the phrase 'temperature differences' exhibits a profound understanding of evaporation.

If a location gets 45c (as per GP's reference) during the day, this doesn't necessarily speak to night time temperatures.

I'll note that Bahawalpur's temperature profile is available at:

For the three hottest months of the year the average lower temperature is around 25C, which suggests quite a low evaporation rate overnight.

It would be great if you could provide some more detailed insights.
