No, not outside, Terry. But isn't the humidity in the UK pretty high and constant? I mean, you're never all that far from the sea.
In the midwestern US we go from an ambient humidity of 20-30% during the fall and winter months to as high as 70% in the spring and summer, as it is now. Constant humidity is no problem, high or low, it's the extreme changes that seem to make wood go a little bonkers.
