Hi, welcome!
If the leaves are curling up, then there is a good chance that they are not getting enough moisture. Although you are coastal, these plants do typically receive direct moisture spray in their natural environment. It would probably be beneficial to your plant to start misting it once a day to supplement any moisture it is not receiving. I say mist, and not water, because I assume that you are meeting it's watering needs. Just mist the leaves to add moisture and it should be fine.
