I have 3 devices that measure the humidity and it is almost always less than 50 percent, usually around 40 to 45 percent in the summer. The current range recorded on my humidity devices is from 39 to 47 percent during the past 36 hours, even though I have experienced a lot of rain the past two days. I never use any humidity control, except the normal air conditioning, which is always set at 79 degrees, day and night. Those are the facts.

Maintaining your relative humidity level between 39 and 47% is somewhat out of range for residential a/c systems in central Florida. Probably need to recalibrate your hygrometers. I needed to do so every six months or so when I felt the need to track RH for my satisfaction. Now I can read it on my programmable t-stat app, but I’m not convinced that it’s accurate.
I also keep my house at 79 degrees F during the day and 77 at night, but my RH is between 58 and 62% when I disable the humidity control feature.
