Things are more casual here generally, which cuts both ways. Bal boots are rare to begin with, so you'll stand out wearing them period. But because it's more casual seasonality of dress doesn't much exist. Additionally we don't get much rain from April to November even when we're not in a drought.
I'd say that outside of wet weather to think of them the same as oxfords. If you'd wear oxfords on a given day and feel like wearing bal boots go right ahead.
