People who dislike or hate rain are often referred to as "pluviophobes" or "ombrophobes." The term "pluviophobia" comes from the Latin word "pluvia," which means rain, and "phobia," which refers to an intense and irrational fear or aversion. Similarly, "ombrophobia" is derived from the Greek word "ombros," meaning rain.
It's important to note that not everyone who dislikes rain has a phobia or fear of it. Some people might simply find rain inconvenient or uncomfortable, while others may enjoy it. Phobias, including pluviophobia or ombrophobia, are specific anxiety disorders that cause distress and can interfere with daily life. If someone's aversion to rain becomes overwhelming or affects their well-being, they may benefit from seeking professional help from a mental health practitioner.
