Depends on the direction of the rain. It can be very dry. I grow
Passiflora incarnata and Cyclamen coum in a complete rain shadow next
to a wall, which enables them to overwinter happily.

Most rain seems to come from the south west, so I suppose shady walls
are more likely to be in rain shadow as well.
