I live near Tampa, Florida and every time we have high humidity my front porch gets soaking wet, hoy can I fix this problem. (if it can be fix)
Really need to know more about the situation, but I am guessing you have a cement slab porch. The water is condensing on the cool cement from the warm, moist air. Not a lot of practical solutions that I am aware of. Tearing out the porch and building one that allows circulation under it might help. An impractical solution would be to imbed heat strip. Hopefully someone will come up with a better solution.
Is your porch enclosed? Screened in?
Any advice given here is general in nature and is not necessarily valid for your given area. If in doubt check with your local codes enforcement department for what is required when doing electrical, plumbing or structural work on your house. Permits may or may not be required in your area and home owners may not be able to DIY some tasks. I have no way of knowing if you have the skills needed to complete the tasks you are asking about, when in doubt seek professional assistance.
My advice may be worth exactly what you pay me for it. :-) For the record I did not stay in a Holiday Inn Express last night.
The only simple solution I can think of is to install a porch ceiling fan.
You have cool concrete and high humidity. Put the two together and you are going to have moisture condensing on it.
Not much you can do about the heavy dew. Just be glad it isn't white and 24" deep.
