Rain causing higher humidity level?

[Pinned27]

Today it started to rain, and right now my petco humidity gauge is reading about 67%.
Does the rain affect humidity that much?
or are these petco humidity gauges not worth a crap?
i also have yet to see it drop below 50%, and all my temps are about 91 to 95 degrees.
i know the humidity should be between 10-40%, but 67% seems much to high.

any suggestions or comments?

That petco stuff is worthless... as for the humidity, don't really worry about it as long as the geckos tank is inside and not outside then it should be fine, but you still need a moist hide.

Any recommendations for a humidity gauge?
And yea its inside, by a window but the window is shut tight.
And yea i still have a moist hide.

Well humidity is the amount of moisture in the air so if its raining outside the humidity would be 100% which could raise the humidity inside if windows are open or leaky

Yes. Yes, it does. It is both a product of and contributor to the relative humidity, directly and indirectly.

Possibly that too. Higher quality hygrometers that produce truly precision readings are fairly delicate and require the occasional maintenance and calibration. The little plastic stick on the back of a tank wall disks should not be entirely trusted... while the percentage measurement listed on the sticker backing isn't going to be entirely reliable, those that function at all will still display representational changes; these changes are just divorced from a system of measurement. So when it shows a change from 30% to 67%, it may not actually be a difference of exactly 37% relative humidity... but it does indicate that the humidity rose.

Also applies to stick-on-the-back thermometers, low quality water chemistry test kits and cheap UV meters. The question ultimately becomes; just how precise do you need your measurements to be in order to accomplish what you're trying to accomplish? Do you need accuracy to one one-hundredth of a percent on a humidity gauge, or one tenth of a degree on a thermometer, or is it adequate for your purposes if it's within five percent and three degrees?

Or if the house isn't airtight. Which... most aren't. Although for a number of reasons ranging from construction materials to our tendency to control the indoor climate and the direction in which gas exchange most commonly occurs, houses tend to be a bit more arid than local external conditions. Not always, obviously, but usually. At least when people are living in them.

If anyone really needs a precision hygrometer, the electronic variants are the way to go, with the cost usually mirroring the accuracy. I like Apogee Instruments field models for common herpetocultural use, because they're easy to use for multiple enclosures and have a good history of reliability and some decent thought going into their design, but there are a lot of options.
