I just saw a really interesting website on the Dew Point. This is the temperature at which the air's RH condenses into dew.
What struck me is that the dew point temperature is dependent on the temperature and relative humidity.
The Dew Point Calculator

Here is another:

Which brings me to why mildew is so unpredictable and why it can spring up in warm and cold weather.
Check it out.
The dew point can often be reached in the root zone because of cooler temperatures at the ground, and is a viable way of watering plants through natural condensation, if the soil/mulch is deep enough.

This calculator is designed to give the approximate values and identify the conditions that would allow condensation to form, leaving vulnerability for mold, mildew or rot.
