The nouns, locale and location, have basically the same meaning, with a slight difference.
Location usually means a specific place, such as “on the corner of the table” or “37 South Main Street”—but this is only a tendency; location can mean any place, of any kind.
Locale usually describes an area near some landmark or event, such as “the locale of the bank” (the neighborhood around the bank) or “the locale for the movie” (the area where they film the movie):
The location of my apartment is 37 S. Main Street.
The locale around my apartment has many trees.
However, in the following sentence example, locale and location are interchangeable:
What is the locale/location for the event?
Keep in mind, a locale is defined relative to something, while a location is not. But, generally, it is okay to use either word in most contexts.
