Normally, coasts have dry weather that it is companion of heat from the Sun. This is why people tend to feel exhausted by only walking some inches around the coast. But, <em>when the sea causes breeze then all the coast refreshes</em>, as the sentence states, so plants and all living things moisturise a little by wet air from the sea.
Therefore the correct noun to use is<em> </em><u><em>"brisa" </em></u><em>("breeze").</em>
