Any chance of quantifying this? I take it "adversely" doesn't mean

I have never seen specific data comparing these two situations. Most dry
storage is seasonal (rather than long-term) and this usually means the
colder months. This then introduces climate and weather factors into the
equation, so any comparison is probably sufficiently multivariate that
meaningful comparisons are not within reach (at least in any reasonably
economic way).

How many dry months can you "trade" for a wet month?

When I am at sea I will readily trade a dry _hour_ for a wet month (and I am
not referring to single malts, laddie).
