The owner has double-paned windows, weather-stripped doors, drapes- generally equipped to protect his niche from the environment, but prefers open windows. There is no central humidity control. There is usually a 24-hour on-shore breeze, so the typical climate will be high RH, about 95% of the year. RH ranges between 55-100% daily, but occasionally there is a breeze from the off-shore direction when RH drops to 20% or below, sometimes for a few days at a time. I've heard two votes for the wet, and I'm tending in that direction. Thanks for you input!
