Dear Bill:

Heavy rain and accompanying heavy seas probably are tough on whales (I say
probably because such weather is also tough on researchers, so there isn't
much information out there on this).  In rainy weather, whales must breathe
in some moisture and raindrops from the air.  But to my knowledge, it's not
enough to interfere with their getting enough air at each surfacing.  And
with every exhalation, or "blow," whales probably get rid of some excess
water in their lungs.

Hope this helps.
