I am a pretty much a wimp in summer and will not take my best scopes outside in such conditions. Nevertheless, the reality is that humidity will still be high from time to time in my house. Though again, I am a wimp and the air con is on quite frequently!
Any opinions of how well a fluoride lens will cope (or not cope) with high humidity will be appreciated.

I think the real danger is mould/fungal infestation in your climate. The fluorite lenses are fully coated but like any lens needs to be kept out of harm's way by storing with desiccant in a good quality case, always throughly dry prior to storage.
I have a sachet of desiccant velcroed to the inside of the objective cap and another in the focuser cap as well as three big bags of desiccant in the Pelican case with the scope at all times.
