Vinyl storage advice needed

[Bol]

I will be going overseas for a year, and will try renting out my apartment while I am away.  So I need to move out and store my records and CDs.  Would people be able to advise me as to what kind of storage facility I need in terms of temperature control?  I am in London, UK, so there aren't as drastic changes in temperatures as in say the American Midwest.  But still there would be some variations through a year.  If anyone has some experience in storing vinyl, I would be super interested to hear.  Thank you very much in advance.

Hi. Preservation librarian here. Likely replying too late for your timeline -- sorry, I've been logged out for a few years.

Your biggest concerns are heat and humidity. Temps in London, to your point, are relatively stable. That said, they got up to 32C (90F) last month. If you've identified an air conditioned space then that's not an issue, clearly. If the conditions are not controlled, then you're going to want to make sure that your materials are supported (i.e not leaning significantly) so they aren't susceptible to warping during warm spells. Mold can develop in environments with sustained relative humidity levels over 60%, so make sure you have some visibility on that.

Yeah, humidity would be my biggest concern.

And welcome back, Brandon. It's been a quick minute or two!
