Based on what I've seen in nature films regarding how great apes (chimpanzees, orangutans, etc) react to rain, and the extreme aversion to being rained on that I've anecdotally seen in several different cultures, I have a suspicion that an aversion to rain--particularly to unwanted/unexpected rain--might be not only instinctual but peculiar and specific, similar to our aversions to spiders and snakes. Or maybe not, but it has definitely stood out to me.
