Around 20% is considered low. 30% to 40%, whilst on the dry side, are tolerable. 50% is comfortable, though that percentage can feel quite humid when the temps are high.

Except during the rainy season most deserts have very low relative humidity.
The relative humidity of chaparral can vary depending on factors such as temperature and time of day. Generally, chaparral regions have relatively low humidity, often ranging between 20% to 60%. However, during cooler or more humid periods such as mornings or after rainfall, the relative humidity can be higher.
If the amount of moisture did not change, the relative humidity would be lower because there would be less moisture in the air relative to how much that hot air could hold.
Relative humidity increases during and after heavy rain.
Most likely wind, although, as a San Francisco resident, I have never heard of this happening. Fog usually moves inland from the sea, then burns up during the afternoon, and comes back in during night.
The average relative humidity for all of Michigan is in the mid to high 70% range. Flint hangs right around 73%.
