pluviofilia 5
If you want to be a technical voice for the "hobby, taste or even paraphilia with the rain", you have your weak points. The main one is the Greco-Latin spawn where pluvius, a, um ("rain") is Latin, but 966; 953; 955; 953; 945; (philia "love, affective inclination") is Greek. Although it is true that hygrophilia already has another meaning and it is necessary to differentiate them, something that hardly justifies the invention when some other synonym could be used as in ombriophilia, by 959; 956; 946; 961; 953; 959; 962; ( ombrios "rainy" ) .
