I have always believed that cracking was most frequently due to dryness,
especially swings from very damp to very dry, rather than humidity. Many of
the states in the northern areas have cracking problems in the winter. Once
you turn on the heat, indoor humidity can drop to virtually zero.
However, I have to admit I have no hard evidence on this but I do have an
anecdote to relate. My family and I moved from Illinois to South Dakota
last year. We had an unusually early and cold winter. Within a month of
turning on the heat, my daughter's oboe cracked almost the full length of
the upper joint. As a result of that, I took a close look at my clarinets
and all seemed dry. So ever since, I have increased the frequency at which
I oil the instruments.
