Rubidoux safe to climb after rain?

Looks like there's rain in the forecast this week. Was looking at Mt. Rubidoux and have never been there. 

MP says its "quartz monzonite", which I have no idea if it's like sandstone where you need to wait a few days until you can climb. Thoughts?

Joshua Tree is quartz monzonite also.  Not like sandstone.  

Rubidoux granite (monzonite) is good to go when wet. Besides, there's hardy a hold big enough to break off anyway!
