Almost sounds like a thin film of rust forming on the rotor. After a few times of applying the brakes the rust is rubbed off and your good to go. Thats happened to mine and would make sense from your description that it only happens during rain but thats just my idea..
That was my guess too :wink
Before you drive off next morning shine a torch (flash light) on the discs (rotors) through the wheels & see if the discs are shiny or have a thin layer of rust on them.
Do 318is have rear disc brakes too?
