Since the variety of azalea was never mentioned, there may be some hope.

Plants which are lime tolerant tend to be more salt tolerance. Southern
Indica Azaleas such as Formosa, G.G. Gebring, and George Tabor are
considered moderately salt tolerant. This means the plants tolerant of
moderate levels of salt spray, such as that received in landscapes
adjacent to the beach front, but which are sheltered by other plants,
structures or natural dunes.

However most azaleas and rhododendrons are not tolerant of salt.
