Fog is not bad Fiat..that is good moisture for them, plus it is daytime, it quickly dries out. Rain on a cold night, that is dicey for the succulents, the roots then gets cold and soaking wet,..but we have no rain in sight, and as long as your media is properly draining, should be good. And even if it rains, it is not that strong when it reaches our area, basically just a drizzle, so they are still good for it. It is the snails and slugs that come out that worries me more.
